I don't really think this is a liberal/conservative issue. I'm what most Americans would call extremely liberal, and yet one of the very few legislators whose views consistently align with my own on matters of encryption and privacy is a tea-party libertarian Republican.
I think the proper political theory axis on which to hang this debate is libertarian-authoritarian, both of which exist in liberal and conservative thought.
Wow I really liked this article. It encapsulates my thoughts and validates some of my suspicions on private data trafficking quite well.
Thinking of Silicon Valley as the both the bad guy and the good in the fight for privacy is quite interesting. On the one hand these big companies fight for anti-surveillance measures and they fight against laws for weakening encryption. On the other hand, they fight against laws designed to curb dissemination of private information and general consumer protection. This dichotomy is really striking to me.
