I strongly disagree. The porn is a huge issue, but there are a lot of actually useful websites where kids and teens can learn about their interests. Gatekeeping all that knowledge would make young people significantly less knowledgeable

One issue with “hacky” methods suggested here I can see is they might disable eCall in the EU. And eCall is actually a safety improvement so for some it might be a very suboptimal compromise. But maybe if enough people show resistance to uncontrolled data collection then some meaningful legislation will be passed.
