And government ID is nothing compared to what people already give them by using it 'anonymously'.
Amen. If you are concerned about associating your ID with Facebook, then you obviously don't use Facebook. It's literally a fucking collection of people's faces. And names. And daily activities. The government can do this for you, and probably already has. This is to cut down on anon troll assholes, and I have no problem with that. When one uses Facebook, you have essentially given away your right to privacy, ESP from state actors, given the nature of the service.
But I will say, I haven't heard about this before today.
