Apple recently announced the relaxation of encryption restrictions, allowing EU users to download apps through third-party app stores and supporting browsers that do not use the WebKit engine, in compliance with the Digital Markets Act (DMA). This adjustment lowers the threshold for encrypted payments, enabling developers to use non-Apple payment systems, but they must pay a 'core technology fee'. Although sideloading has been opened up, Apple still emphasizes that the security of its native ecosystem is higher. This move is seen as a compromise to regulatory pressure, which may affect its global 'Apple Tax' revenue of 30%, while intensifying the ecological competition between iOS and Android systems.
