The hubris in believing your position is so right the only way someone could believe you're wrong is if they're misunderstanding your position.

I don't get an itemized list of all the vendors the restaurant had to pay in order to bring me my meal, I just get a bill for the cost of the food.

It's only complicated if you make it complicated, which you kind of have to do in order to rationalize the belief that FB is being wronged here.
