9th US Circuit Court of Appeals

Big tech firms, including Meta, TikTok, Google, and Snap, are fighting against roughly 3,000 youth safety lawsuits alleging their platforms harmed mental health and were addictive. The litigation gained momentum after a federal court ruled that Section 230 provides 'a defense to liability, not immunity from lawsuits.' These cases focus on how the companies allegedly engineered their algorithms to maximize user engagement using techniques that exploit the brain's reward system.
