On my work PC, they all but forced me to create an account just to watch videos. I could not find a way around it (I didn’t try super hard). I don’t use my personal accounts on that device so I just created a throwaway.
I checked in at a restaurant recently and they asked for my number to text me when our table was ready. As soon as the number finished they had my name and all sorts of info I never gave them. It’s totally out of control.
