It will sting Eisner more if the movie makes a bunch of dough

I doubt it. I'll bet this was a very calculated move on Eisner's part, and while he might miss a lot of money because of it, there's probably a business case that says he'll still to better in the long run. Disney is very branded by their image, so something contraversial like Moore's movie has huge damage potential. My impression of Eisner (which is really limited so take this with a grain of salt) is that he probably doesn't care about the message at all and is merely doing what he thinks is best for the bottom line.
