I absolutely refuse to install Windows 10 on my home computer because I don't want to look after my computer like a child who is getting "programmed" by a spiteful ex-spouse.
However... One thing that I've run into a handful of times that really creeps me out is when a manager says up-front at an interview that they want to hire someone who will think of the team as family. It's fine for the team to get along, but I think it's just creepy for someone to ask me to consider someone I've never met as family. And besides, I *have* a family. I go to an interview because I need *work*.
I recently had Facebook prompt me to add a business associate as a "Facebook Friend".
I discussed with him the matter of how Facebook could have known that we know each other. I never used Facebook to communicate with him in any way, nor did I view his profile, and he says that he never even viewed my profile. We can only guess that the Facebook app on his phone (which I steadfastly refuse to install on mine) scraped my phone number from his contacts list and then Facebook somehow matched it up with my name.
Sad to say, that's exactly what I would expect them to do.
