Perhaps that's because privacy is actually an archaic and backward idea that maintains all of our problems alive. I can't think of a less progressive (more conservative) idea than privacy.
The next most important revolution in human history will be our transition to a completely transparent society.
Considering that we need to get to a transparent society, contributions to the privacy movement only ensures that the transition will be even more difficult and violent.
