Agreed, but isn't this a parental issue? Why aren't parents moving back to a "shared pc in the living room" model?

I absolutely would not allow a kid to have an unregulated smartphone and then further compound the problem at home by allowing them to access it privately and without interruption. Device management enrollment is trivial on iphones.

Having a smart phone is required for taking part in society.

Monitoring said devices is a lot harder, enrolling to device manager doesn’t let me monitor the content of specific apps
