A Massachusetts court ruled on Friday that Meta Platforms must face a lawsuit alleging it deliberately designed addictive features on its Instagram platform, which harm young users’ mental health. Suffolk County Superior Court Judge Peter Krupp denied Meta’s request to dismiss the case brought by Massachusetts Attorney General Andrea Joy Campbell, who claimed Meta violated state consumer protection laws and created a public nuisance.

The lawsuit accuses Meta of intentionally designing features on Instagram, such as push notifications and "like" buttons, to exploit psychological vulnerabilities in teens, including their "fear of missing out." The state also alleges that Meta executives, including CEO Mark Zuckerberg, ignored internal research showing that Instagram’s design was harmful to teens despite being aware of these risks.

Meta’s defense rested heavily on Section 230 of the Communications Decency Act, a federal law that typically shields internet platforms from liability for user-generated content. However, Judge Krupp ruled that the law didn’t apply in this case because Massachusetts was targeting Meta’s own business conduct—such as its failure to protect users and misleading statements about Instagram's safety measures—not third-party content.

Krupp's ruling is significant because it distinguishes between holding platforms accountable for user content and their own business practices, such as misleading public safety claims. This decision allows the lawsuit to proceed, potentially setting a precedent for other cases targeting tech companies for the way they design and market their platforms.

The lawsuit claims that features like push notifications, "likes," and the endless scroll feature were specifically designed to keep young users engaged for longer periods, profiting from their addiction. According to internal Meta data cited by the lawsuit, these features contributed to a deterioration in teen mental health. Yet, executives failed to implement suggested changes to improve user well-being.

Massachusetts is one of several states that pursued separate legal action against Meta after a federal judge in California similarly refused to dismiss a multi-state lawsuit that accuses the company of fueling teen mental health problems. This case adds to growing pressure on tech companies over their responsibility to mitigate harm caused by social media platforms.

With the dismissal denied, Massachusetts can now proceed with its claims against Meta. Attorney General Campbell expressed satisfaction with the ruling, stating that it allows the state to push forward with efforts to hold the company accountable for the alleged harm to young users. A Meta spokesperson, meanwhile, reiterated the company’s disagreement with the ruling but said the evidence will demonstrate Meta’s commitment to supporting young people.
