• Epic Games' Megagrant has made AltStore, a popular alternative app store for iOS devices, available for free. AltStore, developed by developer Riley Testut, allows users to sideload apps and games on their iPhones and iPads without the need for a jailbreak. This move by Epic Games is seen as a way to challenge Apple's control over the iOS app ecosystem.

• The article notes that AltStore has been a popular choice for iOS users who want to access apps and games that are not available on the official App Store. With Epic Games' Megagrant, the development and distribution of AltStore will be supported, making it more accessible to a wider audience. This could potentially lead to increased competition in the iOS app market.

• The article also mentions that Epic Games' support for AltStore is part of its broader efforts to challenge the dominance of Apple and Google in the mobile app market. The company has been engaged in a high-profile legal battle with Apple over its App Store policies, and the Megagrant for AltStore is seen as another step in this ongoing conflict.
