What is supposed to happen here? This article and each of the others linked don't offer much beyond jabs at Amazon.
As far as I can tell, publishers are unhappy with Amazon - period. Two years ago the hot news was about Amazon pricing books too low [1]. Now at least part of the complaint is that Amazon isn't discounting enough and allowing prices to approach list price - which I assume is set by the publisher. Isn't that a publisher problem?
Also, this all reminds me of what we used to hear in the music industry - creators hurting because the label (publisher) they're contracted with is feuding and refusing to eat whatever compromise rather than pass it on directly or indirectly.
Would it be a terrible thing if Amazon pressured books into changing the same way iTunes changed music?
