A group of app developers, including Pure Sweat Basketball, Inc., have filed a class action lawsuit against Apple in the US District Court for the Northern District of California. The lawsuit alleges that Apple has unlawfully monopolized the market for iOS app and in-app product distribution services, resulting in overcharges for consumers due to its 30% commission fee on each paid sale from its store. The plaintiffs argue that Apple's pricing and mandates have stifled competition and prevented the emergence of viable competitors. The lawsuit seeks damages and injunctive relief for violation of federal antitrust law and California's Unfair Competition Law, with the goal of challenging Apple's monopoly and recovering damages for iOS app and in-app-product purchasers who have paid supra-competitive prices.
