The machine itself is on trial — not what teenagers typed into it.
On a Friday morning in Boston, the Massachusetts Supreme Judicial Court handed down a ruling that no state high court had ever issued before: Meta Platforms must stand trial for allegedly engineering Instagram to hook children.
The case was brought by Massachusetts Attorney General Andrea Joy Campbell, and Meta had spent considerable effort trying to kill it before it reached a courtroom. The company's primary weapon was Section 230 of the Communications Decency Act, a 1996 federal law that broadly protects internet platforms from being sued over content their users post. Meta argued the Massachusetts claims fell under that shield. A trial court judge disagreed. Meta appealed. Now the state's highest court has disagreed too, unanimously.
Justice Dalila Argaez Wendlandt, writing for the full court, drew a clear line. The attorney general is not trying to hold Meta responsible for anything a teenager typed or posted. She is targeting the company's own choices — the deliberate architecture of the platform itself. Push notifications timed to pull users back in. The infinite scroll that never offers a natural stopping point. The 'like' button, engineered to trigger the same reward circuitry that slot machines exploit. The lawsuit alleges these were not accidents of design but features built to profit from the psychological vulnerabilities of young people, including their fear of being left out.
Campbell called the ruling a major step toward holding companies accountable for practices she says have fueled a youth mental health crisis while prioritizing revenue over children's welfare. Meta, for its part, did not respond to requests for comment on Friday. The company has consistently denied the core allegations and maintains it takes extensive measures to protect younger users on its platforms.
The Massachusetts case carries particular weight because of what it revealed early on about the company's internal culture. Among its most striking allegations: that CEO Mark Zuckerberg was personally dismissive when concerns were raised about Instagram's effects on users. The lawsuit also claims that Meta's own internal research showed the platform was harming and addicting children — and that senior executives rejected proposed changes that the company's own data suggested would improve teen well-being.
Friday's ruling did not arrive in isolation. It came two weeks after a Los Angeles jury found Meta and Google's parent company Alphabet negligent for building platforms harmful to young people, awarding a combined six million dollars to a 20-year-old woman who said she became addicted to social media during childhood. The day before that verdict, a separate jury in New Mexico found Meta liable for 375 million dollars in civil penalties, in a case brought by that state's attorney general accusing the company of deceiving users about platform safety and enabling child sexual exploitation.
The legal landscape surrounding Meta and youth harm has grown vast. Thousands of cases — filed by individuals, school districts, municipalities, and state governments — are now working through the courts. Thirty-four states are pursuing claims against Meta in federal court. At least nine state attorneys general have filed in state court since 2023, including Iowa's Brenna Bird, a Republican, who filed just this past Wednesday. The Massachusetts case is among the earliest and most closely watched of those.
What the Supreme Judicial Court decided Friday is not that Meta is guilty of anything. It decided that the case can proceed — that the claims Campbell has brought are legally cognizable, that Section 230 does not foreclose them, and that a court can hear them. The trial itself, and whatever verdict it produces, still lies ahead. But for the first time, a state's highest court has said plainly: this question is worth asking in a courtroom.

The Hearth Conversation Another angle on the story
What actually makes this ruling different from all the other lawsuits piling up against Meta?
It's the first time a state supreme court has weighed in on whether Section 230 blocks these kinds of claims. That's not a procedural footnote — it's the legal question that could determine whether thousands of similar cases survive or get thrown out.
So Section 230 was Meta's main defense here?
It was their exit ramp. The argument was essentially: we're just a platform, users create the content, federal law protects us. The court said that argument doesn't fit when you're being sued for how you built the machine, not what people put into it.
What does it mean to be sued for how you built the machine?
Think about the specific features named in the suit — infinite scroll, push notifications, the like button. The allegation is that these weren't neutral tools. They were designed to exploit how a teenager's brain responds to social reward and fear of exclusion. That's conduct, not content.
And Meta's own research apparently showed this was happening?
That's one of the most damaging parts of the lawsuit. The allegation is that internal data confirmed the harm, and that executives — including Zuckerberg himself — were dismissive when people inside the company raised concerns and proposed fixes.
How does this fit with what's been happening in other courts?
The timing is striking. A Los Angeles jury just found Meta negligent two weeks ago. A New Mexico jury hit the company with 375 million dollars in civil penalties the day before that. The legal pressure is coming from multiple directions at once.
Is there a political dimension to this? Are these cases partisan?
Not cleanly. Campbell is a Democrat, but Iowa's attorney general, who filed a similar case just this week, is a Republican. Thirty-four states are pursuing Meta in federal court. This has become one of those issues that cuts across party lines.
What happens next in Massachusetts specifically?
The case goes back to the trial level. The Supreme Judicial Court cleared the path — now Campbell has to actually prove her claims in front of a judge or jury. That's a much harder task than surviving a motion to dismiss.
