The European Commission has accused Apple of stifling competition on its App Store, marking a significant move under the new Digital Markets Act (DMA). The DMA, designed to foster competition by regulating "online gatekeepers", targets tech giants, mainly US-based. Preliminary findings indicate concerns over Apple's restrictions on developers directing customers to promotions outside the App Store. If found guilty, Apple could face fines up to 10% of its global revenue, potentially tens of billions of dollars, with repeat offenses incurring up to 20%. The Commission is also investigating Apple's developer fees and restrictions on alternative app stores. Apple insists it complies with the DMA.
