A federal judge in California has denied a request from plaintiffs to certify a class action lawsuit against Meta Platforms, Inc., which accused the company of misleading users about its privacy safeguards to maintain its market dominance. The judge ruled that the plaintiffs failed to demonstrate an antitrust injury, which is necessary for class certification. This decision comes amid ongoing scrutiny of major tech companies regarding their market practices. In related legal developments, a New York federal court has mandated that advertisers must arbitrate their claims against Google concerning alleged monopolization in digital advertising technology. Additionally, a German federal court indicated support for the country's antitrust regulator in its efforts to impose tighter controls on Apple, as it faces increased scrutiny over its market behavior.
