When players do obnoxious things and claim that "its what my character would have done" that's a problem because they have:Holy false equivalencies, FireLance!
A referee who attempts to maintain verisimilitude is no different than a gamer cockblocking the referee and/or the other players?
Basically, though, it's like a free-lance consulting gig. You get paid whatever you can negotiate with our players, of course.
I don't think people are making the claim that the GM will take this advice too far, but rather that the players will take this advice as an entitlement to do nothing other than sit back and expect to be entertained.
Now, as to whether players sometimes forget that they have to make the game fun too...
Because folks who want passive entertainment so often prefer to haul themselves to a game rather than plop themselves down in front of the far more efficient and accessible purveyors of such - TVs and computers?
It is possible that all of the people who have posted about the same here on EN World are either lying or mistaken, of course.
