The EU announced on Friday that Meta must review the addictive design features of Facebook and Instagram or face a fine. The tech giant breaches the Digital Services Act by targeting features such as infinite scrolling, autoplay, push notifications and highly personalized recommendation algorithms, the European Commission said.

The Commission says these features feed the user’s need to keep scrolling and put the brain on “autopilot mode,” contributing to unhealthy habits and compulsive use. It found that Meta failed to adequately assess the risks posed by the addictive design of its platforms to the physical and mental well-being of users, including minors and vulnerable adults.

The Commission also accused Meta of ignoring evidence about the amount of time minors spend on Instagram and Facebook at night and how features such as Reels and Stories could encourage excessive or compulsive use of the platforms.

“The evidence also shows that Meta’s current mitigation measures failed to effectively address the risks arising from its addictive design,” the Commission wrote. “For example, Instagram and Facebook time management tools, including those enabled by default for teens, can be easily dismissed and do not lead to meaningful reduction or control of service usage.”

It asks Meta to disable key addictive features such as autoplay and infinite scroll by default and introduce effective screen time breaks, as well as modify its recommendation algorithm to focus less on user engagement.

The findings are not final and Meta will now have the opportunity to review the evidence against him and present a formal response. If the Commission’s conclusions are confirmed, Meta faces a fine of up to 6% of its total annual worldwide turnover.

Meta did not immediately respond to TechCrunch’s request for comment.

Friday’s announcement marks the second time this year that the EU Commission has found Meta in breach of its laws. In April, the Commission found that Meta did not prevent children under 13 from using Facebook and Instagram.

Meta has also faced scrutiny in the United States for failing to protect young users on its platforms. Most recently, Meta said in a court filing Monday that four U.S. states are seeking $1.4 trillion in fines over allegations that the tech giant designed Facebook and Instagram to addict young users and that it misled the public about the platforms’ security.
