Meta CEO Mark Zuckerberg has just made his first jury appearance in a landmark case. In a Los Angeles courtroom on Wednesday (February 18, 2026) local time, Zuckerberg engaged in a heated exchange with a plaintiff’s attorney regarding allegations that his platform, Instagram, was intentionally designed to addict and mentally damage child users.
The case stems from a lawsuit filed by a 20-year-old woman (identified as KGM) who claims that early social media use led to a severe addiction. She alleges that the platform’s algorithms exacerbated her depression and fueled suicidal thoughts.
“This trial is in the global spotlight because the outcome will set the tone for thousands of similar lawsuits currently facing tech giants,” the AP reported on Thursday (February 19, 2026).
During the question-and-answer session, plaintiff’s attorney, Mark Lanier, asked pointed questions about Instagram’s addictive nature. However, Zuckerberg appeared very cautious in his answers. He declined to provide a direct answer and expressed his disagreement that the term “addiction” could be applied to Meta’s products, despite internal company discussions about the app’s usage duration.
Zuckerberg was also questioned about the company’s ambition to profit from vulnerable users. In response, Zuckerberg insisted that a reasonable company should help its users. The debate became heated when Lanier asked about Zuckerberg’s financial commitment to victims of the negative impacts of social media, a question the CEO immediately denied, considering it a provocative question.
Another interesting aspect of the trial was the discussion of Zuckerberg’s personality, which is often labeled “robotic” by the public. Attorneys revealed internal documents suggesting Zuckerberg should appear more authentic, direct, and human in his communications. Zuckerberg defended himself by claiming the advice was simply feedback, even joking that he was known for his poor public speaking skills.
Meta, through its attorney, Paul Schmidt, argued that the plaintiff’s mental health issues were not caused by Instagram. They cited medical records that indicated internal problems within the plaintiff’s family life. Meta argued that their platform is often used as an escape or coping mechanism for people experiencing hardship.
Zuckerberg remained defensive regarding his age verification policy. He emphasized that the company’s rules are clear in prohibiting users under 13, even though many children actually fake their ages. He believes the challenge of detecting user deception is a technical problem they are constantly trying to solve, not a deliberate attempt to increase user numbers.
This trial marked the first time Zuckerberg stood before a jury to answer directly for the impact of his platform. In the audience were also parents who had lost their children in tragedies believed to have been triggered by social media. The outcome of this “bellwether trial” will significantly determine the future of social media regulation and the moral responsibility of global technology companies towards young people.
