HN is pretty consistently anti censorship
If I buy a car with a Make Love Not War bumper sticker and cover it with a Peace Through Strength bumper sticker, I have not committed censorship, but if I don't buy the car first, I have.
Two of those reasons are a kind of self-censorship for political reasons tied to who is in power. Democracy needs journalism that's ready to stand up to the people in power or we become a state like North Korea where people can't speak the truth.
