Adam Mosseri, the head of Instagram, testified this week that a feature designed to curb excessive use was adopted by only a small fraction of teenage users before it was made a default setting. His testimony came as Meta, Instagram's parent company, faces a significant trial in the United States concerning allegations that its platforms are designed to be addictive to young people.

The trial, brought by 29 US states, is considered a crucial legal test for the impact of social media on young users. The states accuse Meta of intentionally designing platforms like Instagram and Facebook to hook adolescents, contributing to increased anxiety, depression, and even suicidal thoughts. Furthermore, all 29 states allege that Meta violated federal law by improperly collecting and utilizing personal data from children under 13.

Mosseri, who has led Instagram since 2018, addressed the "Take a Break" feature, which prompts teenage users to close the app after a set period. He acknowledged that prior to its activation by default, the feature was used by only a low single-digit percentage of teen users. He stated that "most teens didn’t want it," but the company proceeded to implement it regardless.

This admission came under questioning from a lawyer representing Colorado. Mosseri also confirmed that Meta had not publicly disclosed the feature's low adoption rate, which reportedly stood at only 1 or 2 percent of accounts. He noted that the "Take a Break" feature, along with others like "Quiet Mode," were later integrated into "Teen Accounts" as default settings, which were launched in 2024 and include parental controls.

The lawsuit seeks approximately $200 billion in damages from Meta. The company has refuted the claims, asserting that its research does not show a clear correlation between adolescent social media use and diminished well-being. Meta maintains that it does not intentionally addict children.

Mosseri's testimony is a focal point in the trial, with legal experts observing its potential impact on the case. The states are attempting to demonstrate that Meta was aware of the addictive nature of its platforms and the potential harm to young users' mental health, yet continued to prioritize user engagement and data collection.

Comparisons have been drawn to other legal battles faced by tech companies concerning user data and platform design. The outcome of this trial could set a precedent for how social media companies are regulated and held accountable for the effects of their products on minors.

Unresolved questions remain regarding the extent of Meta's internal knowledge of the psychological impact of its platforms on teenagers and the specific data used to develop and promote features like "Take a Break." The court's decision will hinge on the evidence presented regarding Meta's intent and the causal link between platform design and adverse mental health outcomes in adolescents.
