That very much smell like any other corporate pinky promise, like Amazon's Ring cameras absolutely not invading privacy, employees won't watch girls on it nor will the company give away videos to police without any third party approval. Pinky promise triple double uber promised!
Right. Good job UK. You just made teenage targeted advertisement for VPN, and you also forgot when you were teenagers too, watching porn too, as is perfectly normal. We all done it, without issues... just leave the poor kids alone ffs. France is next, having passed similar BS laws that do nothing to "protect" anyone but make it worse in privacy and actual protection of those at risk.
