From wiki: The Chaos Communication Congress is an annual meeting of the international hacker scene, organized by the Chaos Computer Club. The congress features a variety of lectures and workshops on technical and political issues.
If a hacker community does lecture on political issue, it is not exactly discussing morality of free expression. They are discussing ways in which you can get busted by the police. They are simply paranoid of conviction.
I can't downvote this comment but someone who can please do so.
