In a landmark legal battle, the CEO of Instagram, Adam Mosseri, has testified in the ongoing trial against its parent company, Meta. The trial, involving 29 US states, alleges that Meta intentionally designed its platforms, including Facebook and Instagram, to be addictive to young users, causing mental health concerns such as anxiety, depression, and even suicide. Mosseri admitted during his testimony that the "Take a Break" feature, aimed at countering addiction, was seldom used by teenagers before it became the default setting in September 2024, three years after its launch. He asserted that most teenagers did not want the feature, but Meta proceeded with its implementation regardless. The states accuse Meta of misleading consumers about platform safety and improperly collecting and employing the personal data of children under 13. They seek approximately $200 billion in damages from Meta, which has denied the accusations of intentionally addicting children. Mosseri acknowledged that the percentage of teenagers using Take a Break was low before it became the default setting, but he stated that safety features were later turned on by default in Teen Accounts, launched in 2024 and equipped with parental controls. Former Meta employees have expressed doubts about the effectiveness of features like Take a Break, suggesting they were difficult to find and not widely used. The trial is expected to last six weeks, with jurors set to deliver an advisory verdict. US District Judge Yvonne Gonzalez Rogers will determine liability, civil penalties, and potential changes to Facebook and Instagram if found liable.
