Arturo Béjar spent four days on the stand in Oakland describing a company culture he called "don't ask, don't tell". The former Meta safety engineer told jurors that Mark Zuckerberg understood the harm his platforms did to children while publicly insisting otherwise. By Wednesday the trial was over, cut short after opening statements had barely finished, because Meta had agreed to pay up to eighteen billion dollars and rebuild core features of Instagram and Facebook for anyone under eighteen. Default two-hour daily limits and bans from midnight until six in the morning. Prompts every fifteen minutes reminding teenagers how long they have been scrolling. Forty-eight states and the District of Columbia signed the deal. Meta admitted no wrongdoing, and its chief legal officer framed the settlement as an offer other platforms should copy voluntarily.

Britain took a different route to the same problem and arrived somewhere much less certain. Parliament this year voted down a blanket ban on social media for under-16s, the option Australia had already implemented. In its place sits the Online Safety Act, enforced by Ofcom, which in March wrote to the largest platforms demanding better age verification and warning of penalties for continued failure. Ofcom's own research found that seventy-two per cent of children aged eight to twelve had social media accounts despite minimum age rules supposedly barring them, and that a fifth of children openly admit lying about their age to get past whatever checks exist. The regulator has issued information requests, published codes of practice, and promised enforcement is coming. What it has not done, and structurally cannot do in the way a state attorney general can, is extract a payment sized to the harm and use it to fund the clinical response.

That distinction matters more than it might first appear, because the money in California is earmarked for youth online safety initiatives, while the money in Britain for the equivalent problem comes from general taxation and lands squarely on the NHS. Andy Burnham's government announced £343m for community mental health expansion in recent weeks, funding a hundred new community mental health centres and fifty-nine emergency department units, much of it aimed at children and young people whose presentations have been rising for a decade. Health Secretary Yvette Cooper has framed the investment as necessary and overdue. What nobody in Whitehall has quite said aloud is that this spending exists in significant part because platform design choices, the same ones a Californian jury was about to examine in detail, have been driving referrals into CAMHS faster than the service can expand to meet them.

The comparison is not simply about money, though the sums are instructive. It is about where the cost of a known harm gets priced and by whom. In America, four days of testimony from a whistleblower who described internal research being suppressed was enough to bring a trillion-dollar company to a settlement table with concrete, timetabled product changes. In Britain, that same body of evidence about addictive design sits alongside years of Ofcom letters and a rejected ban, while ICBs quietly absorb the clinical consequences into commissioning budgets nobody links back to the platforms themselves. The NHS has no equivalent of a state attorney general's office. It cannot subpoena a chief legal officer or extract a settlement fund earmarked for the waiting lists it is trying to shorten.

There is a version of this argument that overstates its case, and it is worth resisting. Meta's settlement does not admit causation, and the mental health pressures facing British children have multiple drivers beyond any one platform. But the structural point stands regardless of how any single company's liability is eventually litigated. The United States has demonstrated, however imperfectly, that a jurisdiction with sufficiently sharp legal tools can make a platform pay something closer to the true cost of the harm it causes and change its product as a condition of settlement. The United Kingdom has chosen a slower, more consultative path through Ofcom, one that relies on voluntary compliance backed by the threat of future fines. Cooper's £343m is a sign that the government understands the scale of the problem. What it has not yet found is a mechanism for making the companies whose design choices help create that demand contribute anything like their share of meeting it.
