>We have parental controls on devices
That's irrelevant because social media regulation is a collective action problem. No individual parent can restrict their kids access to social media without ostracizing it, it only makes sense if all parents together get their kids off these platforms.

Yes, and the wishes of all parents together != the wishes of the UK government which has its own agenda at play in which to weaponize this public outrage for their own benefit(mass surveillance and mass censorship).
The UK government doesn't actually want what's best for all the children of all the parents, otherwise it wouldn't have allowed and even enabled the rape gangs and sweep the issue under the rug in a massive coverup.
