there is a substantially large group of pricky nerds that are in favor of linux for ideological reasons (and nationalist pride, suse started here).
Interestingly enough, Ubuntu started in South Africa but I've never seen it preloaded on a system at any of the computer stores I've been to. In fact, I don't really know anyone who runs Ubuntu as their primary OS.
The fact is, we spend 500B a year on the military so that when we do fight people, it is a massacre. We do not want our guys to die. We want their guys to die.
You shouldn't want their guys to die, you should want their guys to surrender.
We don't really understand it, so we'll give it to the programmers.
