Instagram head Adam Mosseri testified in Meta's social media addiction trial that he was unaware employees had been told by a company lawyer to limit the teen safety data shown to him. The trial, brought by attorneys general from dozens of states, alleges Meta deliberately designed its platforms to hook children despite internal research showing harm to young users, making Mosseri's testimony a significant moment as the first senior executive to take the stand.

A 2023 slide deck presented by Instagram staff found that content on suicide, self-harm and eating disorders reached a disproportionately large teen audience, two and a half times greater than among adults, while teens viewed "non-recommendable" content at 1.5 times the adult rate. A lawyer reportedly told employees to strip these statistics to "limit" Mosseri's exposure, though he denied any involvement in restricting his own access to such information. Design director Francesco Fogu also testified he was told data could only be conveyed to leadership verbally, while separate evidence showed uptake of Instagram's "take a break" feature was extremely low, at just 1.8% of users in 2021 and 0.165% of teens in 2022.
