Google has settled a lawsuit with Epic Games, which accused Google of maintaining a monopoly in app distribution and in-app payments through the Play Store. The settlement includes reforms allowing users to download third-party app stores and developers to offer alternative payment methods within their apps, with Google charging a capped service fee of 9 to 20%. This agreement is expected to have far-reaching effects on the mobile app market and may lead to changes in the business models of both Google's Play Store and Apple's iOS.
