AI Liability Opposition to Motion for Summary Judgment

IN RE: SOCIAL MEDIA ADOLESCENT ADDICTION/PERSONAL INJURY PRODUCTS LIABILITY LITIGATION

🏛 U.S. District Court for the Northern District of California · 📅 2022-10-06 · 📑 Case 4:22-md-03047-YGR, MDL No. 3047

Issue

In *In re: Social Media Adolescent Addiction/Personal Injury Products Liability Litigation*, the Plaintiffs' Steering Committee argues that Meta and co-defendants designed their platforms with features — including infinite scroll, autoplay, algorithmic notification timing, and gamification mechanics — that were unreasonably dangerous for minor users, and that commercially feasible safer alternatives existed and were knowingly bypassed. The legal question is whether that evidence is sufficient to create genuine disputes of material fact on design defect and feasibility, precluding summary judgment in Defendants' favor on core products liability claims.

What Happened

Filed on April 13, 2026, as Amended Exhibit 989 to the Plaintiffs' Omnibus Opposition to Defendants' Motions for Summary Judgment (Dkt. 2480), this exhibit is the expert report of Tim Estes, dated May 16, 2025. Estes, who founded the child-safety platform AngelQ, offers opinions that Defendants' platforms were defectively designed through deliberate deployment of compulsive-engagement mechanics targeting minors, relying in part on Defendants' own internal documents to establish contemporaneous knowledge of foreseeable harm. He further argues that meaningful age verification and parental control mechanisms — including credit card checks, government ID scanning, and federated identity systems — were commercially available and in use by comparable platforms such as Xbox, Apple, and Google Family Link well before Defendants implemented them. The report contends that Defendants' eventual parental controls were opt-in, structurally ineffective, and arrived only after harm was already documented, characterizing their inadequacy not as a missed opportunity but as itself a design defect. Estes cites COPPA, the 2023 U.S. Surgeon General's Advisory, and the Kids Online Safety Act as reinforcing the regulatory and normative baseline against which Defendants' design choices should be measured.

Why It Matters

This report represents a significant moment in the effort to establish that products liability design defect doctrine applies to social media platform architecture — a theory that, if credited at summary judgment, would move the litigation past the threshold question of legal viability and into full merits adjudication. The feasibility argument is particularly consequential: by grounding safer alternative design in real-world commercial comparators that predated the alleged harm period, Plaintiffs aim to foreclose any claim of technological impossibility as a matter of law, converting feasibility into a jury question. Two open doctrinal questions hang over the report's reception: whether courts will apply a minor-specific risk-utility standard for engagement features that serve adult users while foreseeably harming children, and whether COPPA compliance functions as a regulatory floor or a safe harbor that displaces common law claims — neither of which has been definitively resolved in this MDL. The report's individual causation gap and its use of Estes's own platform as a feasibility comparator are predictable pressure points that Defendants will likely press in both Daubert proceedings and in reply briefing.
