A U.S. judge has ruled that Google holds a monopoly over general search services and the Play Store, impacting millions of consumers and developers. This follows a series of antitrust actions against major tech companies, including Google, Meta, and Amazon. Judge James Donato indicated significant changes will be mandated for Google's Play Store, including allowing alternative app stores on Android devices, to foster competition. Google has raised concerns about potential security risks from third-party app stores. Meanwhile, another judge, Amit Mehta, found Google violated the Sherman Act by maintaining its monopoly through distribution agreements. Both cases highlight the ongoing legal scrutiny and potential for significant penalties, including possible divestment of key Google components.
