Meta Faces Landmark Trial as US States Allege Youth Addiction by Design

A coalition of attorneys general from over half

A coalition of attorneys general from over half of US states is taking Meta to court in a landmark jury trial beginning Tuesday, accusing the company behind Instagram and Facebook of engineering its platforms to be habit-forming for minors. The consolidated lawsuit, filed in federal court in Oakland, California, marks the largest legal challenge of its kind against the tech giant, with states arguing that Meta’s design choices have fueled a youth mental health crisis.

The trial is set to unfold over six to eight weeks, with testimony expected from Meta CEO Mark Zuckerberg, Instagram chief Adam Mosseri, and Arturo Béjar, a former employee turned whistleblower who has publicly raised concerns about the platform’s effects on young users. The states allege that Meta prioritized engagement and profit over child safety, deploying features like infinite scroll and algorithmic recommendations that exploit developmental vulnerabilities.

Legal experts suggest this case could set a precedent for how social media companies are held accountable for product design under consumer protection laws. The states seek not only financial penalties but also court-ordered changes to Meta’s practices, including greater transparency and parental controls. Meta has repeatedly denied the allegations, arguing that it has invested in safety tools and that teens themselves report positive experiences on its platforms.

The trial comes amid growing bipartisan scrutiny of tech companies, with Congress holding hearings and other states pursuing similar lawsuits. If the plaintiffs succeed, it could force Meta to alter core features or face further legal action. The outcome may also influence pending legislation aimed at regulating online platforms’ impact on minors.

Observers note that the case’s size—with nearly 30 states participating—underscores a coordinated effort to challenge Big Tech’s influence. For families and advocacy groups, the trial represents a potential turning point in the fight over digital wellbeing, though any remedy could take years to implement as appeals are likely.

As opening arguments begin, all eyes are on the jury’s response to evidence that Meta’s internal research allegedly showed awareness of the risks to young users. The decision, whenever it comes, will likely be dissected not only for its verdict but for the legal reasoning that could shape future accountability for technology companies.
