"My cousin still tracks her 23-year-old daughter's location - I thought that was bananas, but in this article there's a 29-year-old who's being tracked by her mother. WTF??"

My comment is regarding the 23 and 29 yo examples in the parent comment. If you as a 29 yo consent to your mom tracking you in order to get a free phone, then that is your choice. Can't you just disable tracking or buy your own phone?

I clearly was not referring to 'a kid with a part-time minimum wage job.'
