Access to the Internet is not something that the parents are actually capable of restricting. As soon as one kid in the has a phone, their entire peer group is exposed.
The question isn’t about restriction. It’s about who will be teaching these kids about the Internet. The first kid learns from their parents; every other kid learns (mostly) from other kids.
If your kid is the last in their class to have a phone, everything they know about the Internet they will have learned from their peers. They sure as hell aren’t going to tell you they already know about all the things you’ve been trying to hide from them.



Invasion of privacy can be a good teaching moment.
Don’t wait until they’ve embarrassed themselves: take them through their browser history before they’ve even thought about porn. Show them router logs before they include pornhub entries. Show them their tracking history while they were far away from you, out with grandma. Explain that you don’t look at these things, but that this sort of information is available. That if they use their school’s wifi it’s available to their teachers. If they use their friend’s wifi, it’s available to their friend’s dad.
Do it while the information isn’t embarrassing, and they will learn to protect themselves, rather than be upset about your “invasion”.
