BOSTON (AP) — Massachusetts’ highest court heard oral arguments on Friday in the state's lawsuit claiming that Meta designed features on Facebook and Instagram to make them addictive to young users.

The lawsuit, filed in 2023 by Attorney General Andrea Campbell, asserts that Meta's business model was built on creating addiction in users, significantly impacting the lives of teenagers using these platforms.

We are making claims based only on the tools that Meta has developed because its own research shows they encourage addiction to the platform in a variety of ways, said State Solicitor David Kravitz. He clarified that the claims do not pertain to the company's algorithms or content moderation failures.

Meta, on the other hand, strongly disagreed with the allegations, expressing confidence that the evidence will demonstrate its commitment to the well-being of young users. Attorney Mark Mosier argued that the lawsuit mischaracterizes traditional publishing actions, defending the company's rights under the First Amendment.

The Commonwealth would have a better chance of getting around the First Amendment if they alleged that the speech was false or fraudulent, Mosier stated. However, they acknowledge that it is truthful, placing the lawsuit in the heart of First Amendment protections.

Several justices appeared more focused on the notification functions of Meta’s platforms than on the content itself. Justice Dalila Wendlandt remarked on how Meta's algorithms exploit teenagers' fear of missing out (FOMO) through incessant notifications.

It’s not about how to publish but how to attract you to the information, Justice Scott Kafker noted, shifting the focus towards the company's strategies of engagement rather than specific content.

Meta faces multiple lawsuits claiming it has knowingly designed addictive features for children, a move that may shape the future of social media regulations. The lawsuit reflects broader concerns over teen safety and mental health amidst increasing scrutiny of social media platforms.

In light of previous reports indicating harm from platforms like Instagram on teenage mental health, the outcomes of these legal decisions could be pivotal in holding tech companies accountable for user welfare.
