They didn't. No stay-at-home law, and schools for kids under 16 never closed. That's the whole point of the Sweden example. Sweden did NOT have an enforceable stay-at-home order.
Meta AI:
"Literally drove teens to suicide" — Lawsuits allege contribution, not sole causation. Courts have allowed claims that chatbot interactions contributed to psychological distress that preceded suicide to proceed to trial/settlement. That is an allegation of contribution/failure to protect, which is still being litigated.
"Intentionally" — False / unsubstantiated. There is no public evidence, court finding, or company statement showing AI systems were built with the intent to drive teens to suicide. The allegations in all public filings are about negligent design, addictive design, and inadequate safety interventions — the opposite of an intentional plan to cause death.
