Google, Meta and TikTok have filed three federal lawsuits seeking to stop California from enforcing a law that can impose penalties of up to $50,000 per affected child for knowingly giving users under 16 access to personalized feeds, autoplay or other features the state defines as addictive.

The separate complaints, filed Wednesday in San Jose, San Francisco and Los Angeles, ask courts to block Assembly Bill 1709 before it takes effect on Jan. 1, 2027. The companies contend that California has crossed from regulating product design into controlling how online speech is selected and presented, violating the First Amendment and federal protections for publishing decisions.

California says the measure addresses design systems intended to maximize engagement among children. Attorney General Rob Bonta’s office told Reuters that it was reviewing the suits and would defend the state’s child-protection laws. The dispute creates an immediate test of how far states may go when the same recommendation tools can be characterized as both editorial systems and potentially harmful product features.

What the California law requires

The enacted statute prohibits a covered platform from providing an “addictive feature” to a California resident under 16. It specifically includes an addictive feed and autoplay, while authorizing the attorney general to define additional covered features by regulation. A platform may keep an under-16 account only if those features are unavailable.

Before activating covered features, platforms must use age information supplied through California’s separate age-assurance system. If a platform cannot verify a user’s age through that process, the law directs it to rely on an alternative state age determination. Accounts belonging to users under 16 must be deleted unless the platform offers a compliant version without the restricted features. Penalties reach $25,000 per affected child for negligent violations and $50,000 for knowing violations, although courts must consider company size, duration, severity and good-faith compliance.

Three suits share a constitutional theory

The Google, Meta and TikTok complaints make closely related claims. Each argues that recommendations and sequencing are editorial choices protected by the First Amendment, even when software performs the selection. They also invoke Section 230 of the Communications Decency Act, which protects online services from certain liability tied to third-party content and their decisions about publishing it.

The companies frame the law as overbroad because it applies to systems that can also steer younger users toward age-appropriate material. Google says personalized recommendations help YouTube surface suitable videos. Meta argues that California would override its decisions about arranging billions of posts. TikTok says the state cannot suppress protected expression because lawmakers consider it unsuitable for younger audiences. Those are litigation positions, not findings, and the courts have not yet ruled on their merits.

The Associated Press reported that each company also says parents should retain primary control over a child’s online experience. That contention puts parental authority alongside the companies’ speech claims, but it does not resolve whether the state may regulate engagement mechanics that operate continuously and at scale.

California treats engagement design as a safety issue

California’s position begins with a different description of the regulated conduct. The Legislature said algorithmic recommendations, infinite scroll, autoplay and notifications can reinforce compulsive use. When Gov. Gavin Newsom signed the measure in September, his office described it as part of a broader safety package covering social media, companion chatbots, privacy and digitally generated child-exploitation material.

The law does not prohibit minors from accessing every covered platform. It instead requires companies to remove specified engagement features from under-16 accounts. That distinction will matter because California is likely to argue it is regulating how a product captures attention, while the companies will argue those same functions determine which speech users see. The practical operation is inseparable from both: a recommendation system is simultaneously a distribution mechanism, an engagement tool and a content-ranking judgment.

The immediate fight is over timing and scope

The lawsuits arrive less than two months before the scheduled effective date, making requests for preliminary injunctions the first major decisions to watch. To obtain early relief, the companies will generally need to show likely success on the merits and irreparable harm, while courts weigh the state’s interests and the public consequences of delaying enforcement.

A ruling could be narrower than either side’s preferred outcome. A judge might distinguish personalized recommendations from autoplay, examine whether the age-assurance rules create separate burdens, or limit enforcement without invalidating the entire statute. AB 1709 contains a severability clause intended to preserve portions that can function if another provision is struck down.

The stakes extend beyond California. States have adopted differing approaches to age verification, parental consent and youth feeds, while platforms operate national products that are difficult to redesign jurisdiction by jurisdiction. A decision blocking or sustaining California’s model would influence lawmakers elsewhere, but the three trial courts may initially produce different answers. For families and platforms, the only certainty is the calendar: unless a court intervenes, the new restrictions begin Jan. 1.
