concern themselves with
Entitlement is asking for something you don't deserve, like free gear or a mount.
Getting angry over developers removing a feature that's been in the game for years is not entitlement. It's criticism over po world of Warcraft where the game is headed, something many fans concern themselves with.
I hate the precedent this word sets. Now if anyone wants to criticize any decisions a developer makes, people like you are just going to scream out "entitlement" like it's a valid point.
But I guess that's the new buzzword, so you have to use it.
