Instagram Chief Compares Social Media Addiction to Binge-Watching
Instagram head Adam Mosseri testified on Feb. 11, 2026, in a Los Angeles Superior Court trial alleging that major social platforms misled the public about safety and that design choices fostered harmful effects on young users. Mosseri said he differentiates between clinical addiction and problematic use, noting a casual remark that he was "addicted" to a Netflix show does not equal a medical diagnosis. The case targets Meta (Instagram), YouTube, TikTok and Snap; TikTok and Snap previously settled and are no longer involved. Trial exhibits included internal Meta emails debating whether to ban digital filters that might encourage plastic surgery; Mosseri said the company chose a focused ban on some filters and maintained that filters do not drive ad revenue. Plaintiff attorney Mark Lanier questioned executives about product decisions and risks to minors.
High-profile litigation against major social platforms (Meta/Instagram) could set legal or regulatory precedents affecting product design, youth protections and platform ad inventory/revenue models.

Zuckerberg Faces Court Over Teen Social Media Addiction
Meta CEO Mark Zuckerberg testified in Los Angeles Superior Court in a landmark trial examining whether social media products are addictive and harmful to teens. Plaintiff KGM (also known as Kaley), a 20-year-old, sued four social platforms; TikTok and Snap settled before trial while YouTube and Meta are defending. Trial evidence included Meta research saying parental supervision often could not prevent compulsive use and that traumatized teens were more likely to overuse social apps, a 2015 email chain showing Zuckerberg pushed to increase time spent by 12%, and internal estimates that millions of under‑13 children had Instagram accounts. The jury outcome could prompt legal reforms, settlements and platform changes.
Instagram chief Mosseri testifies he didn't hide information
Adam Mosseri, head of Instagram at Meta Platforms Inc., testified on Aug. 25, 2026, at a federal courthouse in Oakland during a landmark social media addiction trial. He stated he does not instruct employees to withhold information that could create legal liability. Mosseri said Meta lawyers reviewing child-safety research would not surprise him for legal reasons but would be concerning if intended to mislead the public. The trial, co-led by California Attorney General Rob Bonta with attorneys general from Colorado, New Jersey, and Kentucky, represents a bipartisan coalition of 29 states. Plaintiffs allege Meta violated COPPA and consumer protection laws, seeking penalties up to $200 billion. Mosseri acknowledged Meta limited internal access to some research after whistleblower Frances Haugen's 2021 document disclosures but said work was centralized, not reduced. In a separate CNBC interview, Haugen expressed skepticism about AI companies' compliance with a White House agreement on AI self-regulation, citing tech companies' tendency to circumvent intent. She praised Anthropic's advocacy for independent auditors but stressed the need for robust oversight.
Instagram's Teen Targeting Under Fire in Lawsuit
During testimony in K.G.M. v. Platforms et al. in Los Angeles County Superior Court, internal documents and emails showed Instagram tracked increasing time‑spent milestones and highlighted a focus on tweens and teens. The evidence cited daily usage rising from 40 minutes per day in 2023 to 46 minutes per day in 2026. The 19‑year‑old plaintiff (K.G.M., “Kaley”) alleges social media use contributed to addiction and mental‑health harm. Snap and TikTok settled before trial; Meta and YouTube executives, including Meta CEO Mark Zuckerberg, provided testimony. Plaintiff lawyers point to internal goals such as “total teen time spent” and emails noting age requirements were hard to enforce. Meta disputes causation and says it has implemented teen protections and age‑collection changes over time.
