Agreed. Bitcoin provides anonymity and people that use it for political or convenience reasons are sometimes looked at suspiciously. But, if I go into Walmart and pay for $150 in groceries in cash, no biggie.

Services like SpiderOak that include anonymity as a feature to a small extent do a disservice so the otherwise laudable principle of "can't I be anonymous sometimes without being a criminal?" Maybe zero-knowledge features would be looked upon less suspiciously if they were just included as a feature, without being advertised as a feature? Well, I think you get my gist?
