A federal appeals court in the United States has cleared the way for thousands of lawsuits against major social media companies, including Meta, Google, and TikTok, to move forward. The suits allege that these platforms were deliberately engineered to be addictive, with particularly harmful effects on younger users.
The US Court of Appeals for the Ninth Circuit, based in San Francisco, ruled on [date] that the companies' attempt to invoke Section 230 of the Communications Decency Act as a shield against liability was premature. The court held that the law provides a defense against liability, not blanket immunity from being sued, and therefore the companies cannot appeal before a final verdict.
The decision affects more than 3,000 consolidated cases filed by school districts, municipalities, states, and individuals across the US. They argue that features like infinite scroll, autoplay, push notifications, and daily streaks are designed to maximize user engagement, contributing to rising rates of anxiety, depression, and body-image issues among young people.
Meta, which owns Facebook and Instagram, had argued that Section 230 grants it broader immunity, allowing an immediate appeal. But the Ninth Circuit disagreed, noting that such appeals are typically only possible after a case concludes. The ruling does not decide the merits of the addiction claims, but it allows the litigation to proceed.
European parallels and regulatory momentum
While this is a US legal development, it resonates across the Atlantic. European regulators and courts have been grappling with similar questions about platform design and youth mental health. The EU's Digital Services Act, which came into force in 2024, imposes stricter obligations on platforms to assess and mitigate systemic risks, including those related to addictive design and the protection of minors.
In several European countries, including France, Germany, and the Netherlands, lawmakers have debated or introduced measures to curb addictive features. For instance, France has considered age verification for social media, and the UK's Online Safety Act (though post-Brexit) includes provisions to protect children from harmful content.
The Ninth Circuit's ruling could influence how European courts interpret the balance between platform immunity and user protection. It also highlights a growing transatlantic consensus that tech companies must be held accountable for the design choices that shape user behavior.
Meta already faces significant financial penalties in the US. In New Mexico, a jury ordered the company to pay $375 million (€325 million) in March for violating the state's Unfair Practices Act, and a judge later added $567 million (€491 million) to a youth mental health abatement fund after ruling that Meta's platforms constituted a public nuisance.
Beyond addiction, separate lawsuits have raised concerns about child safety, such as Snapchat's "Quick Add" feature allegedly facilitating contact between adults and minors. These cases underscore the broader scrutiny of social media's role in society, a debate that is equally intense in European capitals.
For European readers, the outcome of these US cases may offer a preview of legal arguments that could emerge in EU courts. As the Digital Services Act matures, European judges may look to US precedents—or deliberately diverge from them—when interpreting platform responsibilities.
The Ninth Circuit's decision is a procedural one, but it carries substantive weight. It signals that courts are unwilling to let tech giants use Section 230 as a get-out-of-court-free card, a stance that may encourage similar challenges in Europe.
