According to Newsnight, the UK government say they can't block X—despite the deepfake CSAM—because people could evade such a ban using VPNs.
But the #OnlineSafetyAct is working just fine even though people can use VPNs to avoid having to upload photos of their passport (etc.) to some shady unregulated age verification company.
The UK government's internet policies are totally rational and coherent. Nothing to see here. Please don't ask us any more annoying critical questions.
