The copyright is for the vindictive software business. The copyleft is for the vindictive software hacker collective.
Case in point: the apology from Monsoon for having initially refused to make their source code modifications available, and the response from the Digg peanut gallery.
Of course, they, the copyright and copyleft, are eventually going to learn alot from each other. I think they each have something that the other lacks: the copyleft has distributed development man-hours and manpower behind it, while the copyright has lots of ideas to test out, money to devote and markets which need better software for their computing appliances.
Eventually, the two will push computing technology forward. The copyright will lead the way, but their implementation will be half-baked; the copyleft will take what the copyright created and develop it into a standard.
But where is the copycenter, the permissive software licenses, in all this?
Does it simply pick up the slack that the copyright and copyleft drop in their move to progress? Maybe its not as stuck on supposed slights or enemies of “innovation” (EULAs) or “freedom” (GPL).
It just wants to be used.
