Meta, YouTube found liable for addicting child to social media

In a landmark California trial, Meta and YouTube were found liable for negligence and failure to warn users after a jury determined that their algorithmic design choices were engineered to addict children, causing severe mental health distress and self-harm to a young user. What happened The case involved K.G.M. ("Kaley"), identified in reports as a woman who first sued as a minor, alleging that Meta’s Instagram and Google’s YouTube used features such as infinite scroll, autoplay, and recommendation algorithms to keep her compulsively engaged and worsen anxiety and depression. KGM testified that her early use of social media triggered addiction to the technology and exacerbated depression and suicidal thoughts. She said she had developed body dysmorphia as a result of her social media use. From the witness stand, KGM testified that using social media affected her self-worth as she got further drawn into the apps, and she withdrew from friends and family. She developed depression and body dysmorphia as she continuously compared herself to others and used beauty filters to enhance her appearance. On March 25, 2026, a Los Angeles jury found Meta and YouTube liable and awarded damages of approximately $6 million, with Meta responsible for 70% and YouTube 30%. The verdict followed a separate New Mexico ruling a day earlier that found Meta liable for misleading the public and endangering children, adding to the sense that courts are beginning to accept claims that social platforms can directly harm young users. Why it happened During the trial, Kaley's lawyers scrutinised design features that they said intentionally drive compulsive use by children, such as infinite scrolling, autoplay and push notifications. Lawyers also argued that algorithmic recommendations such as Instagram's Explore page learn psychological vulnerabilities and feed young users emotionally triggering content, and that features such as "likes," comments and follower counts "cater to a minor's craving for social validation." KGM's legal team showed the jury internal documents from Meta in which CEO Mark Zuckerberg and other executives described the company's efforts to attract and keep kids and teens on its platforms. One document said: "If we wanna win big with teens, we must bring them in as tweens." Another internal memo showed that 11-year-olds were four times as likely to keep coming back to Instagram compared with competing apps, despite the platform requiring users to be at least 13 years old. What it means The verdict is seen to represent a paradigm-shifting "tobacco moment" for the tech industry, proving that social media platforms can be held legally liable for the harmful behavioral effects of their product designs. For tech developers and deployers, it punctures the absolute legal shield of Section 230 by focusing liability on algorithmic features rather than third-party content. For society and policymakers, it validates growing concerns regarding a youth mental health crisis driven by big tech and serves as a critical bellwether that will likely influence thousands of pending multi-district lawsuits from families, state attorneys general, and public school districts.
