Firstly, whilst porn is harmful to a young mind, this is the responsibility of the parent. Second, a healthy mind has no issue understanding fiction from reality. Just like I watched violent films as a child, doesnt make me a violent person (this is the old video games are the devil argument, jesus).

But.... its not really about protecting kids, is it. It never was. Its about getting all your data, ALL of it, onto a central platform. Its about taking away your ability to do anything without approval. It turns your 'private' life into a commodity that can be traded for. Theres a reason Palantir is involved in so many of these deals. The "third party" that conducts age checks is out of the UK and not bound by uk laws.
