A U.S. appeals court has ruled that Meta, Google, TikTok, and other technology companies must face over 3,000 lawsuits related to social media addiction, particularly involving young users. The court rejected attempts by these companies to claim immunity from such lawsuits, allowing the cases to proceed. This ruling comes amidst growing concerns about the impact of social media on youth mental health, with families suing platforms after tragedies involving children. The fallout from these legal battles could result in significant financial implications for the firms involved.
