Four American families are suing the biggest social media companies on earth for wrongful death after their children killed themselves following years of algorithmic manipulation — and the platforms are still hiding behind federal immunity while Congress sits on its hands.

The Social Media Victims Law Center filed the personal injury and wrongful death suit against Meta, TikTok, Snap, and Google in Delaware Superior Court. The four children — Livi Castro, 13; Riv Kelleher, 14; Nathaniel Chambers, 17; and Dawson Holden, 18 — died by suicide across a 14-month stretch from July 2024 through September 2025 in Texas, North Carolina, Minnesota, and Tennessee. Each had been pulled into social media addiction, severe sleep deprivation, depression, anxiety, and suicidal ideation after years on the platforms, the complaint states.

The lawsuit alleges these companies "ignored repeated warnings from their own researchers, concealed evidence of harm, and built systems that profiled minors during moments of psychological vulnerability." The platforms tracked user behavior to push diet and beauty advertisements, appearance-changing filters, and social comparison features — all engineered to maximize engagement regardless of the human cost.

SMVLC founding attorney Matthew Bergman said it's "particularly salient" that these children died "long after" similar suits had been filed. "These platforms continue to kill kids, despite the platitudes of their executives," Bergman told Fortune. "This is a clear and present danger to the health and safety of children, not just in the United States but around the world."

Google offered the standard corporate condolence: "Providing young people with a safer, healthier experience has always been core to our work," a spokesperson said, pointing to age-appropriate policies and parental controls. Meta, TikTok, and Snap had nothing to say.

Sacha Haworth, executive director of The Tech Oversight Project, put the blame squarely on both the companies and the lawmakers who've enabled them: parents and whistleblowers have met with Congress for years, and "while Congress has dragged its feet, more children have died." The Senate passed the Kids Online Safety Act two years before this lawsuit was filed. The House never voted on it, and the two chambers are now haggling over provisions — a bipartisan failure in plain sight.

Haworth accused Big Tech of "pouring hundreds of millions of dollars into false advertising, deceptive paid partnerships with trusted education programs and political lobbying" — follow the money, and it leads straight to K Street.

The lawsuit landed in Delaware after internal documents from these companies were unsealed in recent state and federal court proceedings. Meta is already on trial in Tennessee, where the state attorney general claims the company deliberately designed Instagram to addict young people. A federal trial in Oakland is set for August, with four states suing over addictive features and illegal data collection on kids under 13.

Section 230 shields platforms from liability for what users post. These families are arguing something different: that the companies themselves built the harm into the product. The algorithms didn't just host content — they chose what to show vulnerable children, when to show it, and how long to keep them scrolling.

The question now is whether a court will finally force Big Tech to answer for what its own engineers built — or whether another round of congressional hearings and corporate sympathy statements is all these families will ever get.
