Yessss, that was my thought. And you try to work out a compromise. Is the profit a problem? What if we donate to charity? Is the material a problem? Ah, you're doing your own encyclopedia. Can we work out some sort of deal where we give you our material and you give us partial credit, a payment as freelancers, something? After all, the book's already written, all you'd have to do is make changes/annotations.
