Zuckerberg Takes Stand in Landmark Social Media Addiction Trial
Finn's Take· TL;DR- Zuckerberg denies Meta intentionally designed Instagram to addict children, claiming focus is on usefulness not engagement time.
- Landmark trial consolidates 1,600+ cases alleging social media platforms use addictive features like infinite scroll and algorithms to harm youth mental health.
- Verdict could reshape how tech companies face liability for social media addiction, affecting hundreds of pending lawsuits from families and school districts.
Tech CEO Faces Jury Over Platform Design Choices
Meta CEO Mark Zuckerberg said the company does not seek to make Instagram addictive to younger users, pushing back against claims that the social media app is designed to be harmful to children during his first-ever testimony before a jury on Wednesday. "I'm focused on building a community that is sustainable," he said when asked whether Meta wants people to be addicted to its social media platforms .
The appearance marked a pivotal moment in the first of a consolidated group of cases — from more than 1,600 plaintiffs, including over 350 families and over 250 school districts — scheduled to be argued before a jury in Los Angeles County Superior Court . In an appearance that was described by NBC News as "combative," the Facebook founder reportedly said that Meta's goal was to make Instagram "useful" not increase the time users are spending in the app .
Lanier spent much of the day pressing Zuckerberg about the company's age verification policies . During his questioning of Zuckerberg, Lanier cited a review from Meta that estimated that more than 4 million people under 13 were using Instagram in 2015 . When confronted about these underage users, Zuckerberg testified that the platform's policy requires users to be at least 13 years old, but admitted that some people lie to get around it .
The Case That Could Change Everything
The landmark trial centers on allegations brought by a plaintiff identified as "KGM," who claims that using social media from a young age caused her to become addicted and harmed her mental health. KGM, who is now 20 years old, alleges that Facebook, Instagram and YouTube — with their recommendation algorithms and infinite scrolling — are designed to be addictive .
Her lawsuit claims she began using social media young, YouTube at age 6, then Instagram at 9. She was also a frequent user of TikTok and Snap. After becoming hooked on the platforms, she said her body image issues, depression and suicidal thoughts worsened . The suit points to features like beauty filters, infinite scroll and auto-play as being tantamount to a "digital casino" .
The plaintiff's lawyers found a way to legally attack tech giants: by treating social media apps as unsafe products, viewing Instagram, YouTube and other services as defective under product liability law. The argument is that tech companies deliberately designed social media sites as harmful and dismissed internal warnings that the services could be problematic for teenagers .
Industry Pushback and Legal Strategy
Instagram CEO Adam Mosseri said he does not believe people can be clinically addicted to social media platforms, instead referring to what he calls "problematic use," when people spend more time on Instagram than they feel good about . YouTube attorney Luis Li told jurors in his opening statement, "It is not social media addiction when it's not social media, and it's not an addiction" .
On the stand, Zuckerberg was questioned about a company document that said improving engagement was among "company goals." But Zuckerberg claimed that the company had "made the conscious decision to move away from those goals, focusing instead on utility" . "If something is valuable, people will use it more because it's useful to them," he said .
TikTok and Snapchat, which had also been named in the lawsuit, settled shortly before trial was scheduled to begin. Terms of the settlements were not disclosed .
What Comes Next
The jury's verdict in the case could shape how some 1,600 other pending cases from families and school districts are resolved . This trial feels like a rehearsal for the next decade of tech liability. Now, 12 jurors are being asked to see "engagement" as something else: a design choice with foreseeable harm, measured in minutes, optimized in experiments, and monetized at scale .
The trial is expected to last several weeks , with Kaley, the plaintiff, expected to deliver the most emotional testimony later in the trial . The outcome could fundamentally reshape how social media companies design their platforms and interact with young users, potentially ending an era where engagement metrics drove product decisions without considering psychological consequences.
