alt Hacker NewsWe might not be paying money, but we don't know what happens to our private data. Maybe it's not used at all, maybe used just internally, maybe could be even sold. Data of millions of users is very very valuable, even just thinking about how much targeted adverts could be placed with it.
It isn't sold directly. There are robust internal controls so random employees can't just snoop on eg ex girlfriends' email or be fired.
