The plaintiffs’ brief alleges that Meta was aware that its platforms were endangering young users, including by exacerbating adolescents’ mental health issues. According to the plaintiffs, Meta frequently detected content related to eating disorders, child sexual abuse, and suicide but refused to remove it. For example, one 2021 internal company survey found that more than 8 percent of respondents aged 13 to 15 had seen someone harm themself or threaten to harm themself on Instagram during the past week. The brief also makes clear that Meta fully understood the addictive nature of its products, with plaintiffs citing a message by one user-experience researcher at the company that Instagram “is a drug” and, “We’re basically pushers.”
