It was a joke.
Also, SW airlines specifically advertises no bag fees. They brag about it. So yeah...people would be pretty upset if they started charging.
Finally, outside of theming and convenience to the parks, I have never held the Disney hotels in that high regard. They have always been "just nice" to me if you put those two things aside. It seems people think they were so amazing at one time and so above the rest. Maybe 30 years ago they were above the competition, or what was competition? But take away the theming and what do you have? An average resort, if that.
