For ham radio you need an exam. It's not just about the medium.

And are you really surprised the hacker community is less preoccupied with rules? :)

I don't think this is about the medium at all. One is all about rules (due to the license conditions), with the other breaking the rules is the very point.

Don't forget the radio community has this darker side too: the radio pirates. They just don't tend to be licensed because you lose it when you get caught. Though many hams started pirating in their younger years and obtained a licence later.
