Apple recently announced the relaxation of encryption restrictions, allowing EU users to download apps through third-party app stores and supporting non-WebKit engine browsers to comply 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'. Despite opening up sideloading features, Apple still emphasizes that the security of its native ecosystem is higher. This move is seen as a compromise to regulatory pressure and may impact its global 30% 'Apple tax' revenue, while intensifying the ecological competition between iOS and Android systems.
