Hacker conference: against authoritarian government, with talk about security, privacy, opsec etc.
Also: can only buy ticket online with credit card and real name, no onsite sell available, your name is probably give to conference administrator for checking ticket, he will probably give it to third parties or keep it for "good reasons", etc.
Don't get me wrong, I like the talks, they are very good. It is just a bit funny for me. They can't try harder to be hackers? Or is it like this in germany always?
That's the official position. I'm pretty sure, but of course I'm not suggesting you do so, that if you pay with a prepaid credit card and call yourself Random Person you will have no problem. As I said in another thread you can also just show up and buy ticket cash at the entrance from whomever sells them, but of course you risk not getting a ticket. Depends on your concerns. I'm pretty sure if you have a better solution but such large scale event you can contribute directly.
The organisation has to still pay their suppliers, and have to comply with anti money laundering laws
The politics of C3 is mixture of older anarcho communist hackers and contemporary progressive statists. So against authoritarian government, if it's right-wing, and privacy to protect against surveillance capitalism (rather than from the state).
So things like bitcoin are not liked as they're outside of the state and money should be a function of a benevolent left-wing state.
Go to the local smaller CCC conferences, where you can pay with things like GNU Taler or cryptocurrency, and the entry is often free anyway, with a donation being appreciated or buying event merch being a nice alternative to simply donating.
I think the hacker spirit is definitely alive & kicking in those smaller CCC events.
