Meta faces high-stakes trial over teen-harm claims that could reshape its platforms

California and three other states open a high-stakes trial accusing Meta of designing features to hook young users and secretly harvesting data from under-13s; Meta defends its safety efforts, citing studies showing mixed teen experiences and saying it deleted many under-13 accounts. The case, a test for a broader multi-state suit, could force changes to the platform (potentially removing infinite scroll) and carry penalties Meta claims could reach trillions, though that figure is disputed. The outcome would add to a wave of lawsuits pressing tech firms on teen mental health and data privacy.
