To clarify: I put E6 and Raising the Stakes out as 100% OGC because I'd like to see what people can do with them.
If someone proceeds to release the exact same .pdfs as a promotion for their website, removing my name from the credits page and putting their own name in its place, there's nothing I can do to stop them so long as my name is there in the Section 15. But that's not exactly in the spirit of the OGL, and you can't expect me to be gung-ho about it.
Now, releasing an edited, improved version with some added examples, maybe some new feats or monsters? That's not far from what I wrote but I'm personally 100% behind that kind of use.
