In a pivotal legal battle taking place in Los Angeles, Adam Mosseri, the CEO of Instagram, has come under scrutiny regarding the platform’s design and its potential contribution to social media addiction. This trial marks a significant moment as families of young users who have suffered mental health issues or tragically died, allege that social media companies knowingly engineered their products to be addictive. The implications of this case could reshape how social media platforms operate and their responsibilities towards younger audiences.

The Trial’s Context

The ongoing trial is part of a series of proceedings involving Meta, Snap, TikTok, and YouTube, which have been targeted by lawsuits from numerous families and school districts. They assert that these platforms have created environments that contribute to addiction and harm the mental wellbeing of young users. The current case spotlights a 20-year-old referred to as KGM, who claims that Instagram’s features, such as endless scrolling, worsened her depression and suicidal thoughts.

During his testimony, Mosseri emphasised a distinction between “clinical addiction” and what he termed “problematic use,” stating that psychologists do not classify social media addiction as an official medical diagnosis. His comments reflect a broader debate ongoing among experts and lawmakers about the potential dangers posed by social media platforms.

Key Testimonies and Allegations

Mosseri was rigorously questioned by Mark Lanier, the plaintiffs’ attorney, who probed whether Instagram prioritised profit over user safety. The CEO responded that the company conducts extensive testing on features intended for younger audiences before their release. “We are trying to be as safe as possible but also censor as little as possible,” he stated, aiming to strike a balance between safety and user experience.

However, many in the courtroom interpreted his responses as reinforcing their fears about Instagram’s impact. Matthew P. Bergman, an attorney representing the plaintiffs, argued that Mosseri’s testimony revealed a troubling commitment to growth at the expense of minors’ safety. He noted, “Instagram’s executives made a conscious decision to put growth over the safety of minors,” underscoring the plaintiffs’ perspective that the platform’s design is fundamentally flawed.

The Broader Implications of Social Media Use

The trial also highlighted disturbing internal communications from Meta employees, who referred to Instagram as a “drug” and acknowledged the addictive aspects of the platform. These revelations have intensified calls for accountability from social media executives. One parent present in the courtroom, John DeMay, whose son Jordan tragically took his life after being targeted in an online sextortion scheme, expressed hope that the trial would shed light on the practices of social media companies. “Now Mr Mosseri is going to have to go on the stand and try to justify why his company was doing the things they were doing to build products that are so addictive,” he remarked.

Despite some recent efforts by Instagram to implement safety features for younger users, critics argue that these measures fall short. A 2025 report from Fairplay, a nonprofit advocating for children’s online safety, found that less than 20% of these tools are fully functional, while a staggering 64% are either ineffective or have been abandoned.

A New Approach to Accountability

The plaintiffs are not solely targeting specific harmful content but are instead challenging the fundamental design choices made by social media companies. This innovative legal strategy has enabled them to circumvent federal protections typically afforded to platforms regarding harmful third-party content. DeMay articulated his frustrations with legislative efforts to regulate tech giants: “I’ve lost a lot of hope and I know other parents have, too.” He believes that the financial implications of the ongoing lawsuits could pressure these companies to enact meaningful changes.

Why it Matters

This trial represents a critical juncture for the future of social media regulation and the responsibility of technology companies towards their younger users. As evidence mounts regarding the detrimental effects of social media on mental health, the outcome of this case could set a precedent for how platforms are designed and operated. The implications extend beyond legal accountability; they raise fundamental questions about the ethical obligations of tech companies in safeguarding the wellbeing of vulnerable populations. With families seeking justice and reform, this trial could catalyse significant shifts in policies governing social media usage and child safety.
