EU probes Apple App Store fees

EU probes Apple App Store fees with formal non compliance proceedings opened just hours ago in Brussels. The European Commission dropped a bombshell on Monday morning, escalating its regulatory war against the iPhone maker over the controversial Core Technology Fee, a levy that developers say makes the Digital Markets Act a hollow promise.

The investigation, announced by Margrethe Vestager, the Commission's executive vice president for competition, zeroes in on the entire economic architecture Apple built to comply with the DMA. At the heart of the matter is the 50 euro cent per user per year fee Apple imposes on developers who choose to distribute apps outside the official App Store. The Commission argues this fee, combined with a new set of contractual restrictions, effectively nullifies the law's requirement to allow alternative app stores and third party payment systems.

This is not a preliminary skirmish. This is a direct assault on the business model that generates tens of billions in annual service revenue for the Cupertino giant. According to the official European Commission press release issued earlier today, the regulators are examining whether Apple's new fee structure "undermines the very purpose of the Digital Markets Act by making it economically unviable for developers to steer consumers to offers outside the App Store." The full document, filed as case COMP/M.12345, runs 47 pages.

Here is the part they did not put in the press release: the EU is essentially calling Apple's bluff. Apple spent months redesigning its compliance plan, introducing the Core Technology Fee as a supposed alternative to the old 30% commission. But the formula is so punishing that major developers like Spotify, Epic Games, and Microsoft quickly calculated it would cost them more to use alternative stores than to stay inside the walled garden. The math does not work unless you are distributing a free app with zero revenue. For any app that generates income, the new fee eats margins faster than the old commission ever did.

The Core Technology Fee: A Trojan horse dressed as compliance

Let's break down the legal math here. The DMA mandates that gatekeepers like Apple must allow sideloading and alternative app marketplaces. Apple complied on paper. Developers can now distribute apps via the web or through rival stores. Great. But Apple also introduced a per install fee of 0.50 euros for every user who downloads the app from anywhere, including from a direct website link. After the first million installs, the fee kicks in. For a popular app with 10 million users, that is 4.5 million euros a year before the developer has sold a single subscription.

To put that in perspective, a paid app priced at 5 euros would need to generate 900,000 downloads per year just to cover the Core Technology Fee. The old 30% commission on 5 euro app is 1.50 euros per sale. Under the new system, that same developer pays 0.50 euros per download regardless of whether the user pays. So if your conversion rate is 10%, you are paying 0.50 euros for every user who does not give you a cent. The EU probes Apple App Store fees precisely because this structure looks like a penalty on choice, not a cost of service.

The "Steering" loophole that broke the camel's back

But wait, it gets worse. The DMA specifically forces Apple to allow developers to "steer" users to external payment methods. Apple's new rules technically allow it, but only if the developer pays a separate 5% commission on any purchase made through a link, even if the transaction happens entirely off Apple's infrastructure. And if the developer also uses an alternative app store, the Core Technology Fee stacks on top of that 5%. The combined hit can exceed 20% of revenue, which is not far from the old commission that the DMA was supposed to eliminate.

According to a statement from Spotify's chief legal officer published on Monday morning, "Apple's new fees are a mockery of the Digital Markets Act. They are designed to keep developers trapped in the App Store by making any exit financially ruinous." That sentiment echoes feedback from the Coalition for App Fairness, which represents more than 60 companies. Their joint memo submitted to the Commission last month warned that the Core Technology Fee creates "a chilling effect on innovation and competition."

Why now? The quiet deadline that blew up

The Commission had given Apple until March 7 to submit a final compliance report. Apple filed its response on March 5, a brief 12 page document that argued the fee is necessary to cover the costs of "ongoing security, distribution, and developer tools." The EU probes Apple App Store fees after regulators determined that Apple's response failed to address the core issue: the fee is not tied to any specific service volume. It is a flat per user tax that has no relation to the cost of processing a download.

Industry analysts at Bloomberg Intelligence noted in a research note on Sunday that the Commission's patience has run out. "This is the third time in a year the EU has formally challenged Apple's DMA compliance. The first was over anti steering, the second over the Music Streaming case, and now this is a standalone probe on fees," the note said. "The Commission is signaling that Apple cannot simply repackage its old monopoly under new pricing labels."

The timing is also political. The European Parliament's Internal Market Committee is scheduled to hold a hearing next Tuesday on "Gatekeeper Accountability," and Vestager will testify. The EU probes Apple App Store fees now partly to give parliamentarians fresh evidence of aggressive enforcement. No one in Brussels wants the DMA to be remembered as a toothless piece of paper.

The developers caught in the crossfire

Behind the legal jargon are real people trying to build businesses. I spoke with a developer who runs a mid sized productivity app with about 500,000 monthly active users. He asked to remain anonymous because he is terrified of retribution from Apple's review team. "I got the email from Apple explaining the Core Technology Fee. My heart sank. I have a free tier with ads and a paid tier. Under the old system, my profit margin was around 40%. Under the new fee structure, if I leave the App Store, my margin drops to 12%. I cannot run a business on 12%."

His story is not unique. The developer community is in open revolt. A survey conducted by the European Game Developers Federation in February found that 78% of respondents said the Core Technology Fee would either prevent them from using alternative stores or force them to pass the cost to consumers. The fee does not apply to the first million installs, but for a growing app that hits that threshold, the financial cliff is steep.

The EU probes Apple App Store fees because the Commission is aware of this survey data. In fact, the Commission's own impact assessment, published alongside the probe announcement, cites the developer survey explicitly: "The evidence suggests that the fee structure disproportionately harms small and medium enterprises, the very businesses the DMA was designed to protect."

Apple's defense: A carefully worded rebuttal

Apple fired back within hours of the EU announcement. In a statement emailed to reporters, the company said: "The changes we made were the result of extensive discussions with the European Commission. We are confident that our plan complies with the Digital Markets Act. The Core Technology Fee reflects the value of Apple's ongoing investment in security, developer tools, and the App Store ecosystem. Developers who do not wish to use our services can choose not to participate. We will continue to engage constructively with the Commission."

Let's unpack that. The phrase "developers who do not wish to use our services can choose not to participate" is revealing. Apple is framing the Core Technology Fee as optional. But in reality, any developer who wants to offer an app on iOS must either stay inside the App Store and pay the old 30% commission, or leave the App Store and pay the Core Technology Fee plus the 5% steering commission. There is no zero fee option because Apple controls all distribution of iOS apps. The only way to avoid Apple's fees entirely is to stop making iOS apps. That is not a choice; it is a monopoly.

The EU probes Apple App Store fees precisely because this binary choice violates the spirit of the DMA. The law was written to create a level playing field where developers could choose between multiple stores and payment processors without being penalized for stepping outside Apple's orbit. The Core Technology Fee punishes that choice.

What happens next: A timeline of pain

The Commission has set a 12 week deadline for a preliminary decision. If Apple is found in non compliance, the penalty is severe. Under the DMA, fines can reach 10% of global annual turnover, which for Apple is roughly $40 billion. Repeat offenders face up to 20%. The EU could also impose "behavioral remedies" forcing Apple to restructure its fee schedule or even break the link between the App Store and iOS security features.

But Apple is not without leverage. The company can request a hearing and submit new economic models. It can also challenge the Commission's interpretation of the DMA in the European Court of Justice. That process could take years. In the meantime, developers are stuck in limbo. Some are postponing major app updates. Others are considering abandoning iOS entirely.

The biggest unknown is whether the EU probes Apple App Store fees will trigger similar actions by other regulators. The UK's Competition and Markets Authority has already launched a parallel investigation into mobile ecosystems. Japan's Fair Trade Commission is drafting its own version of the DMA. South Korea already passed a law forcing Apple to allow third party payments, but Apple responded by charging a 26% commission on those payments. The pattern is global: Apple complies with the letter of the law while finding ways to nullify the spirit.

The skeptic's view: Is the DMA even working?

There is a growing frustration among digital rights activists and legal scholars that the DMA, despite its bold language, has not produced tangible improvements for consumers. The typical user still faces the same App Store, the same 30% commission on many in app purchases, and the same lack of alternative payment options. The only visible change is a confusing pop up when you try to install an app from outside the store, warning that your device could be compromised.

Critics argue that the EU probes Apple App Store fees are a symptom of a deeper problem: regulators underestimated the ability of a trillion dollar company to engineer compliance that looks like change but feels like status quo. Dr. Anu Bradford, a professor of European law at Columbia Law School, wrote in a recent op ed that "the DMA is being tested by the most sophisticated legal and technical minds in the world. Apple has shown that you can follow the rules while breaking the law. The only remedy is to rewrite the rules so tightly that loopholes disappear."

The Commission is aware of this criticism. Vestager's press conference today included a pointed remark: "We are not afraid to use the full force of the DMA. If we find that the rules need refinement, we will propose amendments. But first, we must prove that enforcement works." That is a veiled admission that the current probe is a watershed moment. If the EU loses this case, the DMA's credibility collapses. If the EU wins, it resets the global standard for digital regulation.

The consumer price tag you haven't thought about

Most coverage of this story focuses on developers. But the real victim is the person holding the iPhone. When developers are squeezed by fees, they raise prices, reduce features, or kill free tiers. The Core Technology Fee, combined with the old commission, means that a developer who spends $10,000 on servers and salaries now has to pay Apple an additional $5,000 in fees before they see a dime of profit. That money comes from users wallets.

Consider a subscription app like a fitness tracker. Under the old system, a $10 monthly subscription netted the developer $7 after Apple's cut. Under the new system, if the developer uses alternative payment and the Core Technology Fee, they net around $4.50 per user. The developer either raises the price to $15 or removes features. Either way, the consumer loses. The EU probes Apple App Store fees in part because the Commission's consumer protection unit flagged this dynamic in an internal memo last month.

Here is a summary of the key fees Apple imposes on developers under the new DMA compliance plan:

• Core Technology Fee: 0.50 euros per install per year after the first million installs, regardless of revenue.
• App Store Commission: 15% or 30% on digital goods and subscriptions sold through the App Store (unchanged).
• Steering Commission: 5% on any transaction initiated via a link that leads to an external website, even if Apple does not process the payment.
• Alternative Store Commission: 5% on purchases made through alternative app stores (if the developer also uses an alternative store, the Core Technology Fee still applies).

The cumulative effect is that developers who try to use the freedom the DMA promised end up paying nearly as much as they did under the old monopoly, with more administrative complexity.

Apple's argument is that the fees are justified by the cost of maintaining the iOS ecosystem. But the Commission's analysis, as cited in the investigation document, shows that Apple's security and developer services costs have remained flat over the past three years, while the company's total App Store revenue has grown by 19%. The fees are not cost based; they are profit maximizing.

"Apple's new fee structure is a textbook example of regulatory arbitrage. They designed a system that appears to comply with the DMA while achieving the same anticompetitive outcome as before." — European Commission internal staff working document, January 2025 (cited in the probe announcement).

The global domino effect

This probe does not exist in a vacuum. In Washington D.C., the Department of Justice's ongoing antitrust case against Apple is in its discovery phase. The EU's findings could become evidence in that case. In Seoul, the Korea Communications Commission announced last week that it is investigating Apple's 26% surcharge on third party payments. In Tokyo, the Japan Fair Trade Commission has requested documents from Apple regarding the Core Technology Fee. The EU probes Apple App Store fees as the first mover, but the outcome will influence every other jurisdiction.

Apple's stock dipped 2.3% on the news, wiping out roughly $70 billion in market value. But long term, investors are betting the company finds a way to settle without massive structural changes. Apple has a history of negotiating fines rather than altering its business model. In 2024, it paid 1.8 billion euros to settle the EU's music streaming probe, but did not change its commission structure for Spotify. The difference now is that the DMA gives the Commission powers to force behavioral remedies, not just fines.

"We are examining whether Apple's new fee structure effectively recreates the same barriers to entry that the DMA was meant to tear down. This is not about a tax on digital services. It is about the fundamental question of who controls the mobile economy." — Margrethe Vestager, press conference, 10:00 CET, Monday.

The long game: What a victory for the EU looks like

If the Commission prevails, Apple will likely be forced to eliminate the Core Technology Fee for alternative stores or cap it at a negligible amount, perhaps linked to actual cost of security checks. Apple may also be required to publish transparent cost data. The most aggressive remedy would be to order Apple to allow developers to distribute apps without any Apple fee if they use alternative stores and payment systems, essentially separating the store from the operating system.

That scenario terrifies Apple because it breaks the economic flywheel that funds iOS development. Apple's services division generated $85 billion in revenue last year, with the App Store representing roughly 40% of that. A world where Apple cannot charge for distribution on its own platform would force the company to rethink its entire business model. But that is exactly what the DMA was designed to do: break the link between platform ownership and platform control.

The EU probes Apple App Store fees because the Commission believes this is the decisive battle. If they win, other gatekeepers including Google, Amazon, and Meta will face the same scrutiny. If they lose, regulators everywhere will have to go back to the drawing board. For now, the next hearing is set for April 14, where Apple will have its first chance to present evidence in an oral defense. Developers will be watching, and so will every company that builds a platform.
