The European Union has opened formal proceedings against Meta, threatening substantial fines over features it claims deliberately addict users to Facebook and Instagram. EU regulators say infinite scroll, autoplay video, and algorithmic feeds drive "compulsive use" and "unhealthy habits," particularly among teenagers.

The Digital Services Act, enforced by the EU, empowers regulators to demand design changes that prioritize user wellbeing over engagement metrics. Meta faces potential penalties reaching millions if found in violation. The company now has a window to respond to the regulator's preliminary findings before any final decision.

This marks the most direct regulatory attack on Meta's core business model in Europe. Tech companies routinely defend engagement-focused design as standard industry practice, but the DSA grants Brussels teeth that US regulators lack. The FTC has pursued Meta on privacy grounds, but the EU is targeting the architecture itself.

Infinite scroll—the endless feed that eliminates natural stopping points—has become industry standard across platforms. TikTok, YouTube, and others employ similar mechanics. But the EU argues that when combined with algorithmic ranking and notifications, these features cross into manipulative territory. Meta's own leaked internal research, surfaced by whistleblowers, acknowledged harm to teen mental health, strengthening regulators' case.

The threat lands as Meta faces intensifying regulatory pressure globally. Apple's privacy changes damaged Meta's ad-targeting abilities. TikTok battles potential bans in the US and Europe. Now the company confronts redesigning its flagship products under EU order.

Meta will likely argue that users choose engagement, that alternatives exist, and that design changes would degrade experience. But the EU's framing treats addictive design as a consumer protection issue, not a preference question. If Meta loses, expect other jurisdictions to follow Europe's lead, reshaping how platforms monetize attention.
