Any requests to them to stand up for their readers (like the recent pubisher price control mechanisms on ebooks or DRM schemes or region controls) results in a "Haha, you're kidding right? We have zero control over what the publishers do with our output".
I'm saying, the publishers have nowhere to go if you dont write the books. The relationship is a total inverse of what it should be. Even music artists, normally thought to be clueless/careless on real world matters, are already taking big stances on DRM and their ability to distribute/sell etc and sticking up for their fans. The writers' backwardness (and plain old ludditism) in this regard is mighty strange.
