Defining the fight over addictive social media design
Social media addiction design refers to the deliberate use of app features, notifications, and algorithms that keep users engaged for as long as possible, even when that extended use increases the risk of anxiety, depression, or other harms, especially among young or vulnerable people. The Los Angeles civil trial built around the anonymous plaintiff “K.G.M.” is the first major test of this idea in court. After nearly five weeks of testimony, jurors heard detailed arguments about whether Instagram, YouTube, and other platforms are engineered not only to attract teenagers, but to keep them compulsively scrolling. Her lawyers say prolonged childhood use of these apps fed severe anxiety, depression, body dysmorphic disorder, and suicidal thoughts. For the plaintiff, the key claim is not that social media caused every problem, but that intentionally addictive app features aggravated existing mental health vulnerabilities.
Inside the LA trial: predators, vulnerability, and intent
In closing arguments, plaintiff’s attorney Mark Lanier described social media giants as predators that “never go after the strongest” but hunt “the one that’s weaker, that’s more vulnerable.” In this framing, K.G.M. is a wounded gazelle and the platforms’ addictive app features are the claws. He stressed that the case is about problematic use, not a single cause of harm: social media addiction, he argued, worsened every struggle she already had. The defense pushed back hard. Company lawyers claimed they did not design platforms to harm anyone and pointed to factors such as family instability and genetic risk for mental illness. A psychiatrist who treated K.G.M. for more than two years told the court that social media “played some part” but was not “the majority of the issue,” highlighting how messy causation is when mental health, environment, and platform design intersect.
From tobacco and gambling to social media and AI
Ethicists see clear echoes of older fights over tobacco and gambling in this tech accountability lawsuit. In past decades, courts learned that cigarette makers knew about nicotine’s addictive properties yet denied it, leading to warning labels and strict advertising limits. Similar questions now confront social media companies: what did they know about social media addiction design, and did they quietly use it for corporate gain by chasing engagement at all costs? According to Bernd Stahl of the University of Nottingham, gambling and social media may be following “a similar trajectory” of scrutiny and regulation. His research team argues that generative AI also shows addictive properties, from emotional dependence on chatbot companions to compulsive engagement that replaces real-world relationships, raising the possibility that today’s social media trials are a rehearsal for tomorrow’s AI court battles.
Who should be held responsible for addictive tech?
The LA trial is forcing a larger conversation about where responsibility lies for tech overuse: with corporations, regulators, health systems, or users and parents. Stahl’s work identifies four main groups. Governments and regulators can require labels, restrict advertising, fund research, and apply liability law when harms surface. Big tech companies, however, sit at the center of any solution because they control the data that reveals which platform design ethics reduce or increase addictive patterns—and they profit when engagement rises. Academic researchers provide evidence for courts and policymakers, while civil society groups and families push for safer norms and better digital habits. The outcome of this tech accountability lawsuit could set a precedent: if jurors decide that intentional design choices aimed at young users caused or worsened harm, future platforms—including generative AI tools—may face legal duties to design against addiction rather than for attention.
