What a weird rule. You are intentionally destroying your kid's social, developmental, and interpersonal opportunities because you're unwilling to actually put in the time to parent.
The least you could do is give them a dumb phone, so they are ostracized less. Or better yet, actually teach and parent them how to use a phone, and then give them a phone with locked down permissions to block tiktok/etc that are actually problematic, while still allowing them access to things that allow them to relate to friends and their community. Trust but verify.
What an odd, incorrect assumption. Kids need to be able to socialize. This isn't the 1980s anymore, you can't just go to a mall, there are very few physical third spaces anymore, literally none in some locations.
For a lot of kids, those third spaces are via phone/online. I can absolutely understand wanting to limit exposure to bad influences of phones, that IS good parenting, but you need to offer alternatives, or managed use, or something, or you're socially isolating your kid. Worst case scenario, you're getting them bullied- kids can be cruel (though from what I've seen, not as much as they used to be, thankfully).
The person literally said in another comment:
Now, I'm assuming this is partially a situation of english not being the first language, from some of the grammar, but wanting to have their kids be 'cleanly' broken away from friendships, school stuff, and the very outside world sounds.... look, I'm going to be frank here, their literal goal seems to be socially stunting their kid via helicoptering.
Kids need to learn who they are. You're not trying to raise someone to be a child, you're trying to raise someone to be a healthy, functioning adult, and part of that means going through friendships, even friendship drama, exploring the outside world, etc etc.
