Say you were a guardian or parent and get to decide when a child can get a phone or use a computer and get internet with it. If you wish you can also install software and change router settings to what you see fit.
Some parents decide to forbid the internet completely, others are more relaxed. Some go the helicopter route, and some do not care whatsoever what their kid does online.
What is your policy on letting a child use the internet?
No internet.
I’m normally very progressive, but I think we’ve collected enough data to know for sure that the internet has no good outcomes on children’s development. Furthermore, I don’t want devices spying on children, so any device that eventually connects to the internet is also a nono unless it’s been given an open source operating system and software or completely lacks the ability to record video, audio, or scan for additional devices.
