Google faces significant changes to its Play Store following a lost antitrust appeal by Epic Games. The court mandates that starting next year, Google must enable third-party app stores and allow rehosting of Play Store content. However, users will risk security while sideloading apps, as these sources lack the Play Store's integrated safety features. The specific enforcement of installation whitelists for non-verified apps remains unclear, potentially solidifying Google's control amid increased choices for developers.
