I have a few theories on why DMs hate power creep so much:
Theory 1: A lot of Dungeon Masters have a "my monsters vs. the player characters" attitude. They are on Team Monster, and it's up to them to create interesting challenges and goals for Team Heroes. Power creep makes their job more difficult, because they have to consider more and more angles and contingencies with every new splatbook.
It’s up to the Dm to create interesting challenges for Team Heroes, irrespective of whether DMs are on Team Monster or not.
I could be the PCs greatest cheerleader and supporter and still be expected to make the session interesting and challenging. This is the case without a DM vs Player attitude… in fact it’s much harder when the DM is Team Player because then the DM is less likely to brush of character death as tough luck.
One of the problems is that power creep is often asymmetrical. So I can be Team Player but within the Players one might be making the game trivial in some respects. I actually don’t think power is a problem - I frequently run with higher points buys or free feats at first level. The bigger issue is grandstanding and overshadowing.
