Yeah it's pretty activistic in a progressive way but that goes hand in hand with hacker culture. At least in Europe. It's part of the attraction for me. Though I don't go to CCC but I do to other events.
No it is not. It leads to blind spots and a poor understanding of whats really happening in the world when you are presenting niche ideas as if they are the future thats just around the corner. CCC really needs to vet these speakers better or else just give up and invite anyone to present nonsense.
