Librarians as a whole tend toward a very strong privacy stance. I'm told a large contingent of people at the major library conferences have high opinions of Snowden, for example. And the opposition to the PATRIOT Act is also very common among librarians, out of concern for the privacy of library records.

I've always thought that privacy advocates from the technology sector should work with libraries more than they do. The ALA is aligned on basically all the substantive issues and is frankly a lot better at lobbying and legal matters than most technology groups (which is not too surprising given the positive popular image that libraries have).
