That’s why I said it’s ‘not so terrible’ way, not that it’s a good way.

I don’t see a big issue with people authenticating this way for Facebook or Twitter. They government will basically know that “this person is using Facebook”. They don’t even have to know your username or anything. It gets problematic when we get to more controversial apps and porn so it’s still bad, just not as bad as letting Facebook scan people faces and IDs.
