Privacy online seems to get a bad rap. We're told, "the only people who care about privacy are those who have something to hide." Well, we emphatically disagree. The notion we should not care about privacy is largely promoted by companies who depend on you being their product. It's not about what people want to hide, it's really about being able to choose that your life's work is worth protecting.
