Amazon need to increase its profit. The best way without increasing price from the already steep discount compared listing price are have better discount from huge volume publisher. Publisher balk as their profit margin will be affected. Amazon increase price due to no better term. That is purely logical business decision.
However, the extending shipping time as a punishment part from amazon is not.
