Aptoide, a Portugal-based alternative Android app store, filed a lawsuit in federal court in San Francisco against Google, accusing the company of unlawfully monopolizing the distribution of Android applications and in-app billing systems. Aptoide claims that Google's practices create an "anticompetitive chokehold" that stifles competition and innovation. The lawsuit highlights that Aptoide offers lower commission rates for developers but has suffered harm due to Google's market dominance, which discourages developers from using alternative app stores. Aptoide seeks an injunction against Google's alleged anticompetitive practices and demands unspecified triple damages under U.S. antitrust law. Google has not yet responded to the lawsuit. This legal action is part of broader antitrust scrutiny facing Google, which has faced challenges from other companies and recent court rulings regarding its monopoly status. Following the lawsuit, Alphabet's shares saw an increase, with Class A shares rising 3.63% and Class C shares up 3.56%.
