I don't know, I just can't get fired up about this, I'm sorry. I don't think children have an absolute right to VPNs. There are a ton of things children can't have access to. They don't have full rights as adults, so I feel a bit ambivalent.
As someone with kids I care deeply about the harmful stuff my children will get exposure to. And I'm worried about this as a negative influence, especially to boys, much more than I'm worried about smoking, vaping, drugs, guns, and most other things. This can absolutely wreck your relationships, and it's just not practical to control on a family level. Over 25% of teenagers have ED and it's going up. That can't be good. And for girls it can lead to risky or overall degenerate behavior due to changing expectations and influence.
So many people here pretend like there's no problem.
My point ultimately is that this is a non-solution (websites that don't have verification) (keep in mind they never solved piracy) that is causing collateral damage (non-pornographic content).
