The General Court of the European Union dismissed Apple's legal challenge on Wednesday, cementing the company's designation as a gatekeeper under the DMA. Apple had argued since 2024 that its five App Stores (spanning iPhone, iPad, Mac, Apple TV, and Apple Watch) shouldn't count as a single core platform service subject to Brussels' strictest tech regulations. The court disagreed. iOS also stays labeled as a gateway platform, meaning Apple must allow competing services to interoperate with its operating system whether it likes it or not. The gatekeeper label isn't just bureaucratic theater. It carries teeth. Apple now faces mandatory obligations that gut its business model: no favoring Apple Music over Spotify in search results, no bundling user data from the App Store with iCloud without explicit consent, and mandatory support for alternative app stores on iOS. The DMA explicitly targets companies with annual EU sales exceeding €7.5 billion or market caps above €75 billion, paired with more than 45 million monthly active users and 10,000 business users annually in the bloc. Apple cleared every threshold by a mile. Apple also tried to get iMessage classified differently, challenging its designation as a number-independent interpersonal communications service (NIICS), which would subject the messaging app to EU telecoms regulations. The General Court ruled that challenge inadmissible, meaning it won't even hear arguments on that front. The practical effect: iMessage could face interoperability requirements with rival messaging platforms, though enforcement timelines remain murky. The ruling lands while Apple is already navigating DMA compliance disasters. Its initial response to allowing alternative app stores in Europe triggered a backlash so fierce that even the European Commission called it malicious compliance. Apple proposed commission structures and core technology fees that would've made alternative distribution economically suicidal for most developers. Brussels threatened enforcement action, forcing Apple to revise its terms multiple times throughout 2025 and early 2026. This court defeat closes Apple's last legal escape route from gatekeeper status. The company can still appeal to the European Court of Justice, the EU's highest judicial body, but that's a long-shot Hail Mary with low odds of success. The General Court's reasoning tracks closely with the Commission's original 2023 designation logic, suggesting the legal foundation is solid. Apple now faces a binary choice: genuine compliance with DMA obligations or escalating fines that can hit 10 percent of global annual revenue for repeated violations. At Apple's scale, that's tens of billions in potential penalties.
