This is all based on DME going away. Do you know for a fact that there is another contract? Let's say there is no contract with WDW. Universal signs a contract with Mears and pays the to put universal on the side of all there buses. Disney can't do a thing about that.I'm pretty sure DME is not the only contract Mears has with the mouse. No responsible company is going to burn a bridge they don't have to just to get in a dig, business don't work like that
I'm not saying it would be good business, just that there are things Disney doesn't have control over.
