Meta reached a landmark settlement with over 40 U.S. states and territories in a child safety lawsuit, agreeing to pay up to $17 billion over 10 years. As part of the agreement, Meta will implement significant changes for teen users (ages 13-17) on its social media platforms. These include a default two-hour daily time limit, blocking app access between midnight and 6 a.m., muting notifications during school hours, hiding likes, disabling cosmetic filters, and offering options for video autoplay control and non-algorithmic feeds. Most default protections will roll out within six months, with stricter age verification requirements to follow within a year. Meta is also calling on rivals TikTok and YouTube to adopt similar measures, stating it would then pay $5.3 billion of the settlement and adopt a one-hour default limit.
