And how do you , practically, do that?

Before the internet, parents could exert control by knowing where their children were physically going and who they were talking to over the phone.

Even in the ‘90s and 2000s, parents could control a child’s Internet use by limiting time on the family computer.

Nowadays? Just about every child has a tablet or phone. Even the ones who don’t have devices at home, or have their device use monitored at home, have access to school devices.

Exerting control over a child’s online activity now means monitoring everything they do on every device they have access to, including during the eight hours per day or so that they’re on devices for school work. No parent has time for that. And if the child is deliberately trying to hide some kind of illicit online activity, monitoring becomes an order of magnitude more difficult, because, again, children have access to their own devices, school devices, their friends’ devices, library devices, and dozens of other devices a parent may not even know about, much less be able to monitor.

I’m frankly horrified by the increasing requirements for real identity verification but let’s not pretend being a parent is the same as it was in the '70s.
