Zuckerberg Defends Meta in Landmark Social Media Addiction Trial
Mark Zuckerberg, CEO of Meta Platforms, testified on Wednesday, February 18, 2026, defending his company against allegations that social media platforms are intentionally addictive to children. The trial, unfolding in a California court, centers on a lawsuit claiming Meta and Google’s YouTube knowingly designed their platforms to harm young users.
Shifting Focus from Engagement to Value
Zuckerberg stated that Meta no longer prioritizes maximizing the time users spend on its platforms, such as Instagram, and Facebook. Instead, the company now focuses on “utility” and “value” for users over the long term. He emphasized a commitment to building a “sustainable community.” However, this claim was challenged with internal documents dating from 2015 to 2022, presented by the plaintiffs, which indicated that boosting user engagement, including among teenagers, was a key goal.
Internal Documents Raise Concerns
The lawsuit, known as JCCP 5255, revolves around K.G.M., a 20-year-old plaintiff who alleges that her social media apply, beginning at age 10, led to addiction, anxiety, depression, self-harm, and body dysmorphia 1. Lawyers for K.G.M. Presented evidence, including a 2018 internal document, revealing that Meta estimated 4 million users under the age of 13 were on Instagram in 2015, representing approximately 30% of U.S. 10- to 12-year-olds 2.
Further internal communications highlighted concerns about the potential for harm. One researcher reportedly described Instagram as a “drug” and Meta employees as “pushers,” noting that Instagram chief Adam Mosseri was “freaked out” when the topic of dopamine hits from social media usage was raised 4. Documents also showed that Zuckerberg appeared to push for the restoration of beauty filters, despite internal resistance and concerns about body dysmorphia, citing “competitiveness/growth” as a reason 1.
Legal Implications and Similar Cases
The Los Angeles trial is considered a bellwether case for thousands of similar lawsuits against Meta and other social media companies. A loss could set a precedent for future litigation and potentially lead to significant financial penalties and design changes. TikTok and Snapchat settled with K.G.M. Shortly before the trial began, with the terms of the settlements remaining undisclosed 1.
Additional legal challenges are underway. The state of New Mexico has filed a separate lawsuit against Meta, alleging that the platform failed to remove child sexual abuse material and served as a “prime location for predators” 4. A series of federal cases focusing on the impact of alleged social media addiction on schools and teachers are also scheduled for trial in California this summer 1.
Meta’s Defense
Meta maintains that scientific research does not definitively prove that social media is addictive and argues that other factors could have contributed to K.G.M.’s mental health struggles. The company also points to its investments in child safety as evidence of its commitment to protecting young users 1. Meta also invokes Section 230 of the Communications Decency Act, which generally shields social platforms from liability for user-generated content.
However, the plaintiffs argue that the case is not about content, but rather the addictive design of the platforms themselves, including features like “likes,” infinite scroll, and push notifications.
