Tech Giants Challenge California Law Restricting Algorithmic Feeds for Teens

Three Platforms, One Target

Meta, Google, and TikTok have each filed lawsuits against California Attorney General Rob Bonta to block AB 1709, a state law that prohibits platforms from offering autoplay videos and personalised content feeds to users under 16. Governor Gavin Newsom signed the bill in September 2026, with enforcement scheduled to begin in January 2027. The law mandates that platforms delete accounts of under-16 users who do not disable these features, and imposes penalties of up to 50,000 US dollars per affected minor for non-compliance.

The three companies frame the law as an unconstitutional interference with editorial judgement. Meta argues that AB 1709 violates the First Amendment by dictating how platforms organise and display speech, and contends that Section 230 of the Communications Decency Act, which shields platforms from liability for user-generated content, pre-empts the California statute. TikTok characterises the measure as an attack on curation practices common to bookshops, television networks, and streaming services. Google echoes the argument, noting that autoplay is already disabled by default for minors on YouTube and that parents can block access to YouTube Shorts entirely through existing controls.

The Enforcement Mechanism and Its Critics

AB 1709 does not specify a technical method for age verification, leaving platforms to determine how they will identify users under 16. That ambiguity has drawn criticism from digital rights organisations, which warn that compliance will require expanded data collection from all users, not only teenagers. The Electronic Frontier Foundation argues that the law forces platforms to gather more personal information to differentiate minors from adults, undermining anonymity and concentrating surveillance power in the hands of the companies the bill seeks to regulate.

Rindala Alajaji, the foundation's associate director of state affairs, pointed out that while the stated aim is to reduce harm from algorithmic recommendation systems, the practical effect is to mandate the very data practices that erode privacy. She also highlighted the role of social media in youth-led movements, citing the organising work of Parkland shooting survivors and the global reach of climate activist Greta Thunberg, and described AB 1709 as a functional ban that silences the voices it claims to protect.

A Global Pattern with Mixed Results

California's move follows a wave of national and regional measures aimed at limiting teen exposure to social media features linked to prolonged engagement. In December 2025, Australia enacted the first outright ban on social media for users under 16. France passed similar legislation, but the country's constitutional court struck it down on free expression grounds. The legal uncertainty has left platforms navigating a patchwork of rules, with enforcement timelines and technical requirements varying by jurisdiction.

For Meta, the California litigation adds to an already complex regulatory burden. In late 2025, the company agreed to a settlement of up to 18 billion US dollars to resolve child safety claims brought by 29 US states, a sum that reflects both the scale of the allegations and the company's calculation that a negotiated resolution was preferable to protracted litigation. TikTok and Google face their own child safety scrutiny in multiple markets, and both have introduced parental control features in recent years to pre-empt or respond to regulatory pressure.

The Parental Control Argument

All three platforms assert that AB 1709 undermines parental authority by imposing a one-size-fits-all restriction that overrides family decisions about internet use. Google emphasises that its existing tools already give parents granular control over content types and features, and argues that the California law disables systems designed to surface age-appropriate videos. Meta and TikTok make parallel claims, framing their recommendation algorithms not as addictive mechanisms but as editorial choices that parents should be free to permit or block through platform settings.

The companies contend that the law conflates two distinct issues: the design of recommendation systems and the question of who decides whether a given user should have access to them. By mandating deletion of accounts that retain autoplay or personalised feeds, AB 1709 effectively removes that decision from parents, a move the platforms say exceeds the state's authority to regulate speech.

What Comes Next

Attorney General Bonta's office has said it will defend the law and characterises AB 1709 as a commonsense measure to protect children online. The lawsuits are likely to turn on whether courts accept the platforms' First Amendment arguments or defer to the state's interest in protecting minors from features it deems harmful. Section 230 pre-emption is a narrower but potentially decisive issue: if a court finds that the law treats platforms as publishers by dictating editorial choices, the statute could fall without reaching the broader constitutional questions.

The outcome will set a precedent for similar measures under consideration in other US states and jurisdictions outside the country. If the platforms prevail, legislatures may shift focus to transparency mandates or to restrictions on data collection rather than on content curation. If California wins, the model of feature-specific bans tied to age thresholds is likely to spread, along with the privacy trade-offs that accompany them.
