You'd really enjoy the Chaos Communications Congress. It's something like 20 years old I believe, it's among the best in its niche of security/hacking/thats-great-but-why??-projects, and you won't find a suit there. It is, however, extremely political, with a strong anti-authoritarian and anti-capitalistic message.
