If you empathize with normal users, you realize they don't care the least about any of this. They want to use a convenient service to do things. To post pictures of themselves, to see what their friends and frenemies are up to, what's the new cool thing etc etc. Login should just work, nobody cares what is displayed where, and which site knows what. Normal people (outside the HN) bubble don't care about these things, like privacy and what data they share. It doesn't get them closer to the things they want to do online, that is post things and consume content.
