Amazon may have been acting in the consumer's interest in the fight about textbook pricing, but it's hard to argue they weren't using their monopsony. The publishers were also not cooperating – they were simply setting prices higher than people would like.

I'm also no big fan of these conspiracies where someone like Krugman does something because it may mean a few thousand $ per year for him. That's a cheap attack, and it really doesn't seem plausible that he'd care more about a bit of money than winning the argument.
