Quote - Daz considers add on products as special permission derivatives.  derivatives all the same though.

DAZ can consider it the Queen of England but it still does not give them exclusive rights over third-party textures, which is what you seem to be getting at.  There's nearly a decade of precedent that is all a matter of public record where they've dealt with 3rd party textures as not being "derivative works".  I think it's pretty obvious that DAZ does not consider textures for their models to be in that category - this is how Renderosity makes its money after all - but even if they suddenly reversed themselves and declared all textures and shaders and whatnot to be derivative works, at most they could require the texture artists to cease and desist selling, they couldn't hijack the stuff and run off with it willy-nilly.
