App stores have become the subject of controversy and criticism within antitrust. For instance, app developers such as Spotify and Epic Games (creator of Fortnite) allege that Apple’s 30% cut of all sales in the App Store violates the antitrust laws and is indicative of monopoly power. The claim is that iPhone users are locked into Apple’s walled garden iOS platform, which frees Apple to engage in misconduct in the App Store “aftermarket” to the detriment of users and app developers.
