Europe's General Court dismissed Apple's challenge to the EU's designation of its App Stores and iOS as "gatekeepers" under the Digital Markets Act. The ruling means Apple remains subject to DMA obligations requiring it to allow alternative app stores, support interoperability with rival services, and avoid favoring its own services over competitors. MacRumors reports: Apple took its case to Luxembourg's General Court in 2024 after the European Commission designated its five App Stores -- on the iPhone, iPad, Mac, Apple TV, and Apple Watch -- as a single core platform service under the Digital Markets Act (DMA), a label that brings with it a set of strict obligations. Designated "gatekeepers" are prohibited from favoring their own services over those of rivals, and are prevented from combining personal data across different services. They also have to give users the option to use alternative app stores. Apple also challenged the EU's designation of iOS as a gateway platform, a status that requires the operating system allows rival services to interoperate with it. The company also disputed the classification of iMessage as a number-independent interpersonal communications service, or NIICS, which would subject the app to EU telecoms rules. But the General Court said Apple's actions regarding the iMessage service are inadmissible.Read more of this story at Slashdot.
