Instagram Chief Challenges Concept of Social Media Addiction in Landmark Trial

In a pivotal legal battle unfolding in Los Angeles, Instagram head Adam Mosseri took the stand to challenge the notion that users can become clinically addicted to social media. Testifying on Wednesday, Mosseri argued that the term "addiction" is medically inaccurate, preferring the phrase "problematic use" to describe scenarios where individuals spend more time on the platform than they intend.

The Core of the Legal Dispute

The lawsuit centers on a 20-year-old plaintiff identified as "KGM," representing a bellwether case that could influence the outcome of thousands of similar claims against tech giants. The plaintiffs argue that social media companies are responsible for harms inflicted on children. While TikTok and Snap have previously settled, Meta Platforms and Google’s YouTube remain the primary defendants in this proceeding.

During cross-examination, Mosseri clarified that while he may have used the word "addiction" casually in past interviews, he distinguishes it from the serious clinical addiction he has witnessed in his personal life. He emphasized that prioritizing user safety ultimately benefits the company's long-term revenue.

Revenue and Teen Safety

A significant portion of the testimony addressed the profitability of younger users. Mosseri countered claims that Meta specifically targets teens for profit, stating that teenagers actually generate less advertising revenue than other demographics because they are less likely to click on ads.

However, the plaintiff's legal team presented research suggesting that acquiring users at a young age creates a more valuable, long-term customer base. Mosseri maintained that safety and profitability are not mutually exclusive, asserting, "It's really hard to imagine any instance where prioritizing safety isn't good for revenue."

Concerns Over Cosmetic Filters

The courtroom atmosphere grew tense during discussions regarding cosmetic filters that alter users' appearances. Mosseri defended the company's approach, balancing safety with minimal censorship, but acknowledged the sensitive nature of the topic. This comes after Meta disabled third-party augmented reality filters in January 2025.

The trial is expected to continue next week with testimony from Meta CEO Mark Zuckerberg. The proceedings occur amidst heightened scrutiny of the platform, following reports that its safety features have not always succeeded in blocking age-inappropriate content from reaching minors.
