If we as people who are actually knowledgeable about technology and who care about privacy are sick of ignorant and scare-mongering politicians turning the world in to a version of 1984, we really have to become more active in politics ourselves.. and by doing more than just voting.

You can run for local government, organize, or volunteer, for instance. That will make much greater difference than simply voting or voicing one's displeasure on the internet (though doing both of those can help some too, especially if enough people do so).
