It has got crazy. I recently read an article by a journalist whose son had just started university who was watching his tracking app and worrying when he did not get out of bed on time. Not as old as the 29 year old in the article, but she said she could not concentrate on her work because she was worried he would missing things. There are Whatsapp groups for parents at some universities - apparently discussing your now adult child with a group of strangers is normal.
I asked my daughter (also at her first term at university right now) what she though of the idea of having a tracking app on her phone, and (as I expected) there was no way to tolerate this. I think children who have been tracked normalise this. IMO is stalking once they are adults.
I think the perception that kids (or adults!) need constant entertainment is also harmful.
