Apple Inc. litigation
Epic Games sues both Apple Inc. and Google in an antitrust case after the removal of "Fortnite" from the Apple App Store and Google Play earlier in the day, alleging that the two companies hold an unfair monopoly over development for their respective ecosystems. The game was removed for implementing a feature allowing Epic to directly sell microtransactions while bypassing the 30% cut imposed on developers per transaction by both Apple and Google.
