Instagram head Adam Mosseri begins testimony at Meta child social media addiction trial

OAKLAND, California, Aug 25 : Instagram's top executive, Adam Mosseri, took the witness stand on Tuesday to testify in a trial over whether Meta Platforms designed Instagram and Facebook to addict children without proper regard for their safety.

Mosseri, the head of Instagram since 2018, is a central witness in the lawsuit by 29 U.S. states, in what experts call the biggest legal test yet of social media's effects on young users.

Four of the states — California, Colorado, Kentucky and New Jersey — have accused Meta of designing the platforms to hook young users, fueling anxiety, depression and even suicide, while misleading consumers about their safety.

All 29 states say Meta violated federal law by improperly collecting and using personal data of children under 13 while they used its platforms.

The states have indicated they could seek nearly $200 billion in civil penalties.

Meta has rejected accusations it sought to addict children in pursuit of profit, and said its research showed no clear link between adolescents' social media use and a lack of well-being.

The trial in the Oakland, California, federal court is expected to continue through much of September.

Jurors are expected to issue an advisory verdict. U.S. District Judge Yvonne Gonzalez Rogers will decide whether Meta is liable and, if so, determine any civil penalties and changes to Facebook and Instagram.

INSTAGRAM DESIGN CHIEF TESTIFIES ABOUT DATA

Prior to Mosseri's testimony, Instagram's director of product design, Francesco Fogu, testified about a presentation on teenagers' safety that his team prepared in 2023 for Instagram leadership.

Under questioning from Jason Slothouber, a lawyer for the state of Colorado, Fogu acknowledged the removal of data from a slide showing that teenage Instagram users saw 1.5 times more bullying, suicide, hate, nudity and violent content than adult users.

He also said Instagram knew that fewer people would use its "take a break" feature by not making it the default setting.

In February, Mosseri testified in a Los Angeles trial where a jury ordered Meta ​and Alphabet's Google to pay $6 million to a 20-year-old woman who said she became addicted to Instagram and YouTube as a child. Jurors found Meta and Google negligent in designing their platforms.

Mosseri disputed suggestions that Instagram did not care about children's safety, and defended its design choices against accusations by company insiders that its features were harmful.

He said Instagram's products and policies evolve, and "we try to focus on the most important issues."

Earlier this month, a New Mexico judge ordered Meta to pay $567 million to address teenagers' mental health after that state's attorney general called its platforms a public nuisance.

Tennessee is also suing Meta, raising similar claims about Instagram, in a case on trial in Nashville.
