Meta, TikTok, YouTube Head to Trial Over Teen Harm

Meta Platforms, TikTok, and YouTube will face courtroom scrutiny this week over claims that their platforms contribute to a youth mental health crisis. This trial is a new phase in a national debate over children’s screen time and social media design.

The case, filed in California Superior Court in Los Angeles County, centers on a 19-year-old woman identified as K.G.M. She alleges that she became addicted to the companies’ platforms at a young age because of their design features, according to court filings. She says the apps fueled her depression and suicidal thoughts and is seeking to hold the companies liable.

The lawsuit is the first of several similar cases expected to go to trial this year. It will be the first time major tech companies defend themselves in court against claims that their products caused harm to children, said the plaintiff’s attorney, Matthew Bergman.

“They will be under a level of scrutiny that does not exist when you testify in front of Congress,” Bergman told Reuters.

Jurors will decide whether the companies were negligent in offering products that harmed K.G.M.’s mental health. They will also weigh whether her use of the apps was a substantial factor in her condition compared with other influences, including third-party content and offline factors.

“This is really a test case,” said Clay Calvert, a media lawyer at the American Enterprise Institute. “We’re going to see what happens with these theories” that social media platforms caused the plaintiff harm.

Meta chief executive Mark Zuckerberg is expected to testify. Meta has said its products did not cause K.G.M.’s mental health challenges. Snap chief executive Evan Spiegel was also expected to testify, though Snap settled with the plaintiff in January. The company declined to comment on the settlement.

YouTube plans to argue that its platform differs fundamentally from apps like Instagram and TikTok and should not be grouped with them. TikTok declined to comment on its courtroom strategy.

As the trial begins, the companies are also seeking to shape public opinion. Meta and TikTok have sponsored parent-focused safety workshops and promoted tools designed to limit teen screen time. YouTube’s parent, Google, has partnered with the Girl Scouts to promote online safety education.

Critics say those efforts complicate public trust. “These companies are using every lever of influence that you can imagine,” said Julie Scelfo of Mothers Against Media Addiction. “It can be very confusing for parents who to trust.”

The verdict could influence how future cases against social media platforms unfold.
