A New Mexico judge spent last week doing something no court had done before: ordering a major social media platform to actually change how it works, not just pay for the damage it caused. Judge Bryan Biedscheid’s ruling hit Meta with $567 million in penalties and, more consequentially, a specific list of product changes including eliminating push notifications for minors during nighttime and school hours, hidden “like counts” by default, and a 90-hour monthly cap on combined Facebook and Instagram use for users under 18. The metaphor Biedscheid reached for says everything about how the court saw this case: he compared the psychological harm to kids using Meta’s platforms to a factory’s pollution. Companies don’t just get fined for that. They get ordered to clean it up.

This adds to, rather than replaces, an earlier $375 million jury verdict from March that found Meta knowingly harmed young users’ mental health while misleading the public about the risks. Meta says it’s confident in its record and plans to appeal, which is the company’s standard posture at this point. All they seem to do is deny, defend, appeal, repeat. But what makes Biedscheid’s order different from prior penalties is the legal theory underneath it. New Mexico argued Meta’s platforms constitute a “public nuisance,” the same framework used historically against literal polluters, and the judge bought it. Attorney Joe Rice, who’s worked historic tobacco and opioid litigation, says that framing gives attorneys general nationwide “a new path forward.” Using the nuisance law lets against sites like Facebook allows the plaintiffs to target the design of a product itself, not just individual instances of harm, which is exactly the argument critics have been trying to make about addictive platform design for years.

The ripple effects are already visible. Tennessee’s trial against Meta is underway. Jury selection in a separate multistate federal case, including California, started this week, with New Mexico’s Attorney General confirming he’d already spoken directly with California’s AG about the ruling. A school district’s case begins in February. Every one of these is now proceeding with a real-world example of what a judge is willing to order, not just theorize about. Legal experts say that’s likely to shape how plaintiffs argue their own cases, remedies included.

But this ruling isn’t going to impact everyone. It only applies to users in New Mexico, with no enforcement deadline attached, and identifying who’s actually in-state relies on imperfect tools like IP address matching. More strikingly, Biedscheid explicitly declined to touch autoplay, infinite scroll, and algorithmic recommendation, which are the design features researchers consistently flag as the actual addiction engine. The reasoning? That restricting Meta alone while competitors keep using the same tools would unfairly disadvantage the company. Psychologist Sophia Choukas-Bradley called that omission disappointing, noting those exact features are what’s most linked to problematic teen use. The ruling treats the symptoms it could reach and leaves the underlying mechanism largely intact.

What’s happening here is similar to the age verification laws being implemented by states. Congress is refusing to do anything about these companies (the SCREEN Act is stalled in the Senate Commerce Committee) and state AGs are doing the work federal lawmakers have spent years declining to do, one lawsuit at a time, because a courtroom win is achievable in a way a federal bill apparently isn’t.

So when accountability only comes state-by-state, lawsuit-by-lawsuit, while the underlying product stays engineered the same way everywhere else, you have to wonder if this is actually reform, or just proof of how much easier it is to sue a company than to legislate one?
