I posed this same question and the best answer (for a UK citizen) was to write to my MP. I did that and got a canned response back that addressed none of my points. I agree that it seems futile. I'm vehemently opposed to censorship but am powerless to stop it as an individual. It seems like it's already a done deal. We're not just talking about stopping something in its tracks, but rolling it back in the other direction. The amount of inertia required to do that is completely overwhelming.
Writing to your MP (or governor, or senator) is akin to a slave begging his master. I don't mean to say you're a slave, but generations later, people may see this arrangement we have with our governments in this very way. It doesn't matter that we were told to believe our governments work for us. It doesn't take long to realize that we were told this precisely because it's not so. The power they have is so much greater that it'd be completely unnatural if they ever listened to what the people were asking them to do. They don't care. They only care that you think things are getting better or at least not getting worse. They don't care about what things really are. So I suggest people stop fooling themselves about civilized societies and democracies. There are none.
