Court orders Zuckerberg, Mosseri, and Spiegel to testify in January social media addiction trial
A Los Angeles judge has ruled that Meta CEO Mark Zuckerberg, Instagram chief Adam Mosseri, and Snap CEO Evan Spiegel must testify in a trial set to begin in January. The case centers on social media safety, alleged addictive design, and potential harms to young users.
Judge Carolyn B. Kuhl wrote that a CEO’s testimony can be “uniquely relevant,” noting that knowledge of harms — and failures to mitigate them — could establish negligence or ratification of negligent conduct. Lawyers for Meta and Snap had argued the executives should be spared, warning it could set a precedent for future cases.
Key points
- Who must testify: Mark Zuckerberg (Meta), Adam Mosseri (Instagram), Evan Spiegel (Snap).
- When/where: Trial begins January in Los Angeles.
- Focus: Whether platform design, policies, and enforcement contributed to addictive use and youth safety harms.
- Why it’s notable: First of many youth-harm lawsuits headed to trial; outcomes could shape platform policies and legal standards.
Why it matters
Requiring CEOs to testify under oath could surface internal research, risk assessments, and decision-making around features such as recommendation algorithms, time-on-platform mechanics, age-gating, and parental controls. Findings may influence future design changes, transparency, and regulatory action.
What to watch next
- Scope of testimony: Pretrial motions that could limit or expand CEO questioning.
- Discovery: Any internal documents or studies on youth well-being and engagement tactics.
- Potential remedies: Settlement vs. verdict; possible mandates around age verification, default time limits, or algorithmic opt-outs.
