TikTok has joined Google and Meta Platforms in filing separate lawsuits against the state of California, seeking to block enforcement of a new law intended to limit the risk of addicting children under the age of sixteen to online platforms. The law, known as Assembly Bill 1709, prohibits platforms from offering underage children what it describes as psychologically exploitative features that could lead to compulsive use, including personal recommendations and sending videos through autoplay features. It also requires the deletion of children’s accounts that employ those features. The three companies filed their complaints on Wednesday, arguing that the law wrongly compels them to honour the state’s preferred means of presenting content to children and substitutes the state’s judgment for that of parents. They contend that the law violates the free speech protections of the First Amendment to the US Constitution, as well as Section 230 of the federal Communications Decency Act, which broadly shields online platforms from liability over user content.
The legal challenge represents a significant escalation in the long-running battle between tech companies and lawmakers over the impact of social media on young people. California enacted the measure in September as part of a broader push by states to address concerns about youth mental health and compulsive screen use, and the law was crafted with the explicit goal of curbing features that regulators believe are designed to keep children scrolling, watching and engaging for extended periods. For the companies, however, the legislation is an overreach that strikes at the core of how their platforms function. In its complaint, Meta argued that the state cannot, consistent with the First Amendment, override its editorial judgments about how to curate and display billions of posts of third-party speech. Google, which owns YouTube and operates as a unit of Alphabet, and TikTok, a unit of China’s ByteDance, made similar arguments in their respective filings. The companies are not challenging the state’s authority to protect children in principle but rather the specific mechanism by which California seeks to do so, framing the law as a government mandate on content presentation rather than a genuine child safety measure.
What makes this case particularly fraught is the tension between two legitimate concerns. On one side sits the growing body of evidence and public anxiety about the effects of algorithmic feeds and autoplay features on developing minds, concerns that have prompted parents, educators and lawmakers to demand action. On the other sits a deeply rooted legal tradition that protects platforms from being compelled to present content in ways the government prefers, a principle that has shielded speech across mediums for decades. The companies argue that parents, not the state, should decide what their children see online, and that the law’s requirements would force them to strip features that adults also use and value. California’s attorney general was not available for comment on the lawsuits, leaving the state’s defence to be articulated in court filings yet to come.
The timing of the challenge is notable. It arrives as public pressure on social media companies has reached a fever pitch, with school districts, paediatric associations and state attorneys general across the country pursuing their own actions against the industry. California’s law was seen by its supporters as a model that other states might follow, and the industry’s decision to fight it in court rather than comply suggests that the companies believe the legal principles at stake are worth the public relations risk of opposing a child safety measure. TikTok, in particular, finds itself in a delicate position, having faced years of scrutiny over its Chinese ownership and its effects on younger users, and its participation in the lawsuit alongside Google and Meta places it firmly in the camp of platforms resisting regulation rather than accommodating it.
The legal questions at the heart of the case are complex and unlikely to be resolved quickly. Courts have generally been sceptical of laws that dictate how platforms must present content, but they have also shown deference to legislative efforts aimed at protecting minors, particularly when the harms alleged are concrete and well documented. The outcome may hinge on whether judges view the law’s requirements as a reasonable safeguard for children or as an unconstitutional intrusion into editorial discretion. For now, the law remains on the books but unenforced against the three companies that have challenged it, and the families and advocates who pushed for its passage are left waiting to see whether their victory in the legislature will survive in the courtroom. What is clear is that the debate over children and social media has moved decisively into the legal arena, and the resolution of this case will shape not only California’s approach but the broader national conversation about who bears responsibility for the digital environment in which young people grow up.
