Apple is introducing changes for iPhone users in the European Union, allowing them to download apps from alternative app stores. This move aims to comply with the EU's Digital Markets Act (DMA) and potentially avoid substantial fines. The DMA seeks to promote competition by preventing gatekeeper companies from favoring their own services. This change marks a significant shift in Apple's long-standing policy of requiring all apps to be downloaded through its official App Store, giving EU consumers more choice and potentially impacting the app development ecosystem.
