Four US states have taken Meta to federal court, alleging the company deliberately designed Instagram and Facebook with addictive features that harm children and teenagers. The trial, which began on August 18 in Oakland, California, represents the most significant legal challenge Meta has faced over claims that its platforms cause mental health damage to young users. California, Colorado, Kentucky, and New Jersey are collectively seeking penalties estimated between $200 billion and $1.4 trillion.
The core allegation is that Meta knew its platforms were causing harm and chose profits over protection, violating the Children’s Online Privacy Protection Act (COPPA) by collecting data on users under 13. The states also claim Meta concealed known mental health risks associated with its platforms.
Trial Background
The trial stems from a broader multi-district lawsuit initiated in 2023, originally involving 29 states. The four states selected for this initial trial are test cases, and their outcome will shape how hundreds of remaining claims proceed. Mark Zuckerberg is scheduled to testify during the trial, which is expected to run four to six weeks.
Meta’s defense centers on the argument that it has implemented multiple safety features across its platforms, denying the core allegations. However, even if the final penalty is lower than $1.4 trillion, the operational reforms the states are seeking could prove more consequential, representing a fundamental shift in how tech companies design their products.
Regulatory Context
The trial arrives amid a broader global regulatory push to constrain how tech platforms interact with minors. Australia has moved to ban social media for children under 16, and the European Union’s Digital Services Act imposes stringent obligations on platforms regarding minor safety.
