Choosing a Tin Can for a child that doesn't have a phone isn't restricting them, it's empowering them with a new form of communication to chat to their friends. Getting my 10 year old a bicycle instead of a car isn't a restriction.
Compared to getting them nothing, yes. But the OP's point is that this doesn't prevent the child from mentally comparing themselves to peers that have a smartphone, and viewing their Tin Can as a "restriction" imposed by their parents.
Which it is. I don't understand the need to wink-wink-nudge-nudge pretend it's anything else by the others in this thread. Just own it, restrictions aren't bad by default.
It's no use having an argument with thig guy. He simply has a more modern* definition of what "restricted" means.
*I don't know what to call it. It's like those people that buy a car with heated seats locked down by subscription and calling it "a feature" because some cars don't have them at all.
