It’s very hard to control kids internet access. Impossible really. Even if you do it fine at home, once they go to school it’s whatever policies the school has. Most require laptops and provide internet access.
I feel uncomfortable about the idea of controlling children, even my own. Certainly there is a requirement to protect children from others but I feel like putting in guard rails to prevent children from themselves only leads to making things taboo and, as a result, more interesting.
That's objectively not true. You can just use your own DNS server and lock the settings app either through android mdm policies or an locker app.
> it’s whatever policies the school has.
so the school takes on that responsibility, as deputized by the parents.
Kids don't get unfettered access to the streets while at school. They can't take their bikes and ride out at will. What makes the internet and devices any different? The devices provided by the school should be lockdown-able, and kids should not be provided their own device unless there's a parental lock (which is enabled during school hours, and is similarly locked down).
