I think it goes somewhat back to the "toolkit" approach of 3E though, too -- if I'm importing some feats or spells from product X to use in my homebrew world, most likely I'm importing the "crunch" and making up my own "fluff" or "flavor". I think some people feel that creating "crunch" is hard while creating "flavor" is easy, and thus they don't ascribe much value to it. Which is kind of ironic, if you think about it -- the open gaming license protects "flavor" better than it protects "crunch" and yet there may be a perception that the later is more "valuable" in some way...
