What is the cause of action here? > Thirty-three states including California and New York are suing Meta Platforms Inc. for harming young people's mental health and contributing to the youth mental health crisis by knowingly designing features on Instagram and Facebook that cause children to be addicted to its platforms. The lawsuit, filed in federal court in California, also claims that Meta routinely collects data on children under 13 without their parents' consent, in violation of federal law. The federal privacy law part is crystal clear. But there is no description, or even mention, of what laws are being violated related to addictive products. Is this federal law? State law? What does the law say?
