Massachusetts’ highest court heard arguments in a lawsuit accusing Meta of designing Facebook and Instagram features to hook young users, a case brought by Attorney General Andrea Campbell. State lawyers said internal research shows features — notably notifications and endless feeds — exploit adolescents’ fear of missing out. Meta pushed back, arguing the claims impinge on traditional publishing and First Amendment protections. Several justices focused on product-design features rather than content, questioning whether notification systems and UI mechanics can be regulated as consumer protection rather than speech. The outcome could shape campus policies and student-support strategies around digital wellbeing. Source: court proceedings and AG filings.
