Nonprofit advocacy group Public Knowledge argues Google should be compelled to divest its Chrome browser. They filed a friend-of-the-court brief in an antitrust appeal. Public Knowledge believes an independent Chrome would improve user privacy and decision-making. They highlighted Google's reversal on blocking third-party cookies as an example of conflicts of interest. The group contends Google's control over Chrome and its advertising business is problematic. A federal judge previously rejected the idea of forcing Google to sell Chrome. However, Public Knowledge urges the appellate court to reconsider divestiture. They argue an independent entity would prioritize user interests in privacy decisions. This comes as Google appeals a remedies order from a lower court. The original order prohibited exclusive distribution contracts but allowed payments to Apple and Mozilla. The Justice Department and states also want these payments banned. Conversely, Mozilla argues that removing these payments could force them out of the browser market. They cite a study predicting dramatic revenue declines if they switch default search engines. Google maintains its market position was won fairly.
