Social media addiction trial: Adam Mosseri says social media is not “clinically addictive” and that Meta was careful to test features used by young people
Instagram's chief executive said on Wednesday that social media was not “clinically addictive,” refuting claims …
Context & Ripple Effects
The Los Angeles proceeding has made Meta’s youth-product practices a central point of scrutiny. Before testimony began, the company promoted its Teen Accounts through a large paid-ad campaign, adding a public-facing safety message alongside its courtroom defense of product decisions promotion of Instagram’s Teen Accounts ahead of trial.
The testimony also extends a long-running disagreement over how platforms should characterize harmful use: Zuckerberg had previously called the research inconclusive, while Dorsey acknowledged that platforms can be addictive an earlier split between platform leaders over addictiveness.
First-order effects
- Meta gains trial testimony from Instagram’s chief executive contesting the clinical-addiction framing and defending testing of features used by young people.
- The case’s factual focus tightens around what Meta tested, how it assessed youth-facing features, and whether those practices support its safety defense.
Second-order effects
- Plaintiffs can use the distinction between clinical addiction and product-driven engagement to press a narrower question: whether design and testing practices created foreseeable youth harms, regardless of diagnostic labels.
- Meta’s later trial position—that growing Instagram engagement is not a company goal and that identified underage users are removed—makes youth safeguards and internal product objectives central evidence for both sides Zuckerberg’s testimony on engagement and underage accounts.
Third-order effects
- If this litigation pattern persists, platform-safety disputes may turn less on whether social media meets a clinical definition of addiction and more on auditable evidence of youth-design choices, testing, and enforcement.
- That would increase the strategic value of formalized consent and age-assurance processes, though the corpus does not establish how courts will weigh Meta’s testing claims.
The trend: Youth-safety litigation is shifting the debate from broad claims about platform addiction toward the governance and evidence behind product design for minors.
