During a court appearance on Wednesday, Meta CEO Mark Zuckerberg refuted claims made by a lawyer suggesting that he provided misleading information to Congress regarding the design of the company’s social media platforms. This occurred during a significant trial concerning youth addiction to social media.
Zuckerberg faced questions about his previous statements to Congress during a hearing in 2024, where he stated that the company did not instruct its teams to maximize user time on its applications. Mark Lanier, the lawyer representing a woman who accuses Meta of negatively impacting her mental health during her childhood, presented emails from 2014 and 2015 where Zuckerberg outlined goals to increase app usage by double-digit percentages.
Zuckerberg clarified that although Meta had previously set targets related to user time spent on the app, the company has since altered its strategy. He strongly disagreed with any insinuation that his testimony was inaccurate.
This court appearance marked the first time the billionaire Facebook founder testified in court about Instagram’s impact on the mental health of young users. The outcome of the jury trial in Los Angeles carries high stakes for Meta, with potential damages and implications for Big Tech’s legal defense against claims of user harm.
The lawsuit is part of a wider global movement challenging social media platforms over their effects on children’s mental health. Various countries, like Australia and Spain, are implementing restrictions on social media access for underage users. In the U.S., Florida has enacted laws preventing users under 14 from accessing certain platforms, prompting legal challenges from tech industry groups.
The case revolves around a California woman who alleges that Meta’s Instagram and Google’s YouTube targeted children to increase profits despite knowing the detrimental effects of social media on mental health. She claims that using these apps exacerbated her depression and suicidal thoughts, seeking accountability from the companies.
Both Meta and Google have denied the allegations, highlighting their efforts to enhance user safety through feature additions. Meta often cites research findings that do not conclusively link social media to negative impacts on children’s mental health.
This lawsuit serves as a pivotal test case among a series of similar claims against tech giants like Meta, Google, Snap, and TikTok. Numerous lawsuits in the U.S. accuse these companies of contributing to a youth mental health crisis.
Investigations have uncovered internal documents showing Meta’s awareness of potential harms associated with their platforms. Recent revelations include findings that Instagram content negatively affected teenagers’ body image perception. Testimonies from Meta executives have addressed issues like the lack of correlation between parental supervision and teens’ social media habits.
During the trial, Meta’s legal team argued that the woman’s health issues stemmed from a troubled childhood, with social media serving as a positive outlet for her creativity.
