Uh, maybe I should have worded that differently. I didn't mean "extremist" as a value judgement. Just someone being on the extreme end of the spectrum "all software should be free" vs. "all software should be proprietary and patented".
Edit: And now I see that in my grandparent post I wrote that the BSD and GPL people are extremists on opposite sides of the spectrum, which doesn't really match the above. I don't know what I was thinking when I wrote that, what I wanted to write was that they are both on the same end of the spectrum.
If anything the folks who want software copyrights and patents are the "extreme" POV, no?
I mean, on the hardware level we're talking about MOV instructions, eh?
