Its a tragedy of the commons situation. The benefits of being offline are dampened by the kid being out of the loop
Besides, there are many ways to still keep your kids connected to their friends without feeding the beast.
And I say this as a parent.
I actually am curious about your experience on this. Basically, I'm worried that I'll try to make restrictions in the future, and it'll just be a war of attrition that I lose, since internet platforms touch so many parts of social life, especially for the young. Maybe things will be different in a decade.
