I firmly disagree. Hiding things is a hack; the actual solution is to change society such that exposure entails no significant consequences.

Sure, as a band-aid to make existing real people feel secure? Hiding things and keeping them hidden is fine. It's just an indicator of how far we as a society still have to go.

Do remember: "it's our responsibility to hide things to support freedom and democracy" is the exact argument used by the government against things like Wikileaks. The exact argument.
