The censorship is not happening by the community, it is coming from the admins that are on the reddit payroll. There are some posts that are auto-deleted based off of keywords during some of the more turbulent times in reddit.
You got a source for that?

And, for the record, I have no problems with the /r/technology mods implementing such a filter. I want to read about technology, not politics. I actually unsubscribed from /r/technology some time before the filter was put in place (it was one of the very few defaults I'd unsubbed from, actually) because I was sick of it being overrun by political content.
It's hardly what I'd call true censorship either way, since people are freely and openly discussing the very "censorship" and the content being censored elsewhere on reddit.
