I think there's lots of information that should be censored, and if I were made data czar of the world I would surely not be corrupt and do a diligent and thoughtful job removing only what must be removed for the good of the world.

But I would not trust any corporation (sometimes it's profitable to remove something so they retain control of some market) or government (sometimes it secures their power to keep people unaware of some facts about their actions) to do the same. Would you?
