Because it’s not about the kids.

The UK, or any government, could instead use the money for OSA to create a protocol/mandate that phone and net providers need to adhere to, which enables parents to restrict to adult content. Heck, phone-only sims and adult traffic control administered via “parent accounts” would deal with almost the entire problem seeing how most young people use phones for internet access anyways instead of laptops and desktops.

But it’s not about the kids. It’s about control and having an excuse to abolish privacy.
