The European Union’s tech regulator told Meta on Friday to make big changes to Facebook and Instagram’s “addictive” features — or face steep fines. The European Commission called out specific features including “highly personalized recommendations, autoplay and infinite scroll” that allegedly keep users hooked. Firms can face fines of up to 6% of their annual revenue if they don’t comply with the EU’s Digital Services Act. The Commission said Meta needs to nix features like infinite scroll and roll out new “screen time breaks” and tweak its recommendation system to be “less engagement oriented.” The Commission’s investigation indicated that Meta did not adequately assess the risks of its addictive design on the physical and mental wellbeing of users, including minors and vulnerable adults. Based on Meta’s fiscal 2025 revenue, it faces a potential fine of about $12 billion. EU investigators also found that Meta “disregarded available information about the time minors spend on Instagram or Facebook at night.” Meta pushed back, stating it disagrees with the preliminary findings and noted it has launched a Teen Accounts feature.
