What's stopping kids from simply hanging out with one another?
Pre-social-media I grew up with no TV, only Christian music, limited movies and a whole host of other things that isolated me from my peers. It didn't do anything but build resentment towards my parents and make me thankful they have no say in my life anymore.
I don't now the best approach with kids these days since I don't have any. But I strongly doubt it's the "strict no" route.
