I think it might be because ham radio is still barely legal and the community wants to keep the few freedoms they have so they try not to piss off any groups of interest. Whereas pretty much everything hacking-related is already a felony thanks to DMCA and other similar laws, so they don't have much to lose.

Hackers were much more rebellious in former days before such laws were past. My opinion the reason why hackers got more "civilized" is that you could earn quite a lot of money by getting (and staying in) a job in big tech.
