Teen social media claims are brought on three theories: defective product design (engagement features built to addict minors), failure to warn parents of known risks, and negligence in operating a product foreseeably used by children. All three avoid Section 230 immunity by targeting design rather than user content.
Theory one: defective design
A product is defectively designed when its risks outweigh its benefits and a safer alternative design was available. Plaintiffs argue that engagement-maximising features — endless feeds, streak mechanics, algorithmic escalation — were chosen over readily available safer configurations such as chronological feeds, session limits, and default-off notifications for minors.
Theory two: failure to warn
Manufacturers must warn about risks they know of and users do not. The claim here is that internal research identified serious mental-health effects on teenage users, particularly teenage girls, and that neither those users nor their parents were ever told.
Theory three: negligence
Ordinary negligence asks whether a company acted with reasonable care given what it knew. Where a platform knows minors make up a substantial share of its users, plaintiffs argue that reasonable care requires age-appropriate defaults rather than the same optimisation applied to adults.
Why Section 230 does not end the conversation
Section 230 of the Communications Decency Act shields platforms from liability for content published by their users. It does not shield them from liability for their own product decisions. Courts have allowed design-based claims to proceed on exactly that distinction, which is why the pleadings in this litigation are written the way they are.
