I think people with Macs are more inclined to spend money on stuff they like. Linux seems to be at the opposite end of the spectrum i.e. all software should be free. The PC crowd is the middle ground. I've always thought that it was a waste to include some sort of copy protection scheme anyway ... don't challenge the hackers they'll win. Others think that copy protection just keeps the honest people honest ... but mostly I just hear about honest people getting angry because they're the ones being punished, not the hackers.
