I've found this generally true as well. The "moral quandary" moments most DMs try to set up often come down to choosing a kick to the head or a kick to the testicles. However, that's dime-store morality; any DM can set up a can't win situation.
The second is what gets me. I found a lot of grim, dark, low-magic GMs come real close to saying "This world is grim and dark. FOR YOU! I will continue to use the Monster Manual and create NPC wizards as normal" I don't mind settings where the deck is stacked, or even where magic is rare and NO one really has any, but settings where you are expected to fight liches with only a party of fighters (no rangers or paladins allowed), a half-sorcerer/half rogue (mandatory equal levels) and a +1 butterknife is NOT the definition of fun I like.
Ya, that is how I feel.
Plus, the whole player/dm adversarial situation is not cool to be the player, as it's against someone with infinite power and such. The rules do state when you die or lose as a player. It doesn't say how you win forever. Moreso, the gm can 'win' by simply making a player loose. Especally if its not the whole party. And sometimes even if it is, the gm is still fine if the 'show goes on'.
Players have characters, gm's have stories. How many times does grim and gritty kill gm's stories prematurely compared to pcs?
