Now that I've thought about it a bit more:
Det, who precisely are you referring to when you talk about "the community" with all their closed source models and desire for CA work?
IW & Gundam are explicitly avoiding anything GPL (plus Gundam is sharing everything that's smoth's to share, as seen in the mod forum, and IW has said they're open to others using their code & work once they've released). So it's not them.
I've covered S44, so you know we're not the closed source stealers.
PURE has been accounted for by Argh's epic post in general - he's not using any of CA's work, and also making sure that *A doesn't use any of his.
*A (setting aside CA for a moment) mods really don't need to care about a license, since they're already illegal, so saying that "you took GPL code, now you need to be GPL" is silly, because they can't really GPL anything.
Evo is sharing openly as far as I know.
All of KDR's work is his own, and almost universally released under PD.
As far as I can tell, the only project you could have been referring to is EE, since fang has said a few times that he doesn't want other people using his work without permission, but uses the morph gadget a lot.
I apologize if I missed some other major project, but I feel like you're making an inaccurate characterization here, Det - almost all of the big spring engine projects are either very deliberately not using any of CA's work, or are using an open development model (or share what work that they are able to), or both. So it seems silly to say that the community as a whole is trying to steal CA's work without sharing in return.
When people such as the S44 team, Forb, KDR, smoth, or the IW guys (not that they post much in these things <_<) criticize the use of the GPL, It is inaccurate to simply dismiss us as leechers who don't want to share in return; nobody here can fairly claim the high moral ground (except perhaps KDR

).
