I had plenty of friends when I was young that had restrictions on "TV time". My parents, in contrast, were very "hands-off". I've never heard people who are now adults who had "TV time" restrictions express a lot of FOMO or regret about it. Some frame it as "my parents were strict" or "my parents were a little overbearing" but that's about it.
Obviously I understand that it's not the same thing since phones are a 2-way medium and can sometimes be a lynchpin for communication these days, but it's not that crazy or unprecedented either.
What's talked about less (and I suspect the cause of a lot of reluctance to take phones away) is how parents now track their kids' whereabouts using smartphones and apps[1].
