Is it really so shocking that Disney's main motivation is money? It's a company not a person with thoughts and feelings.
WDW and DL are both the same company. They are just drastically different from each other. They offered to drop black out dates at WDW for the end of the parade, not because they care about those APers more, but because they have way less APs and much more space and can afford to do so. And they didn't do that out of the kindness of their hearts either. They did it to drum up good will and most likely try to increase AP sales. Dropping black out dates at DL for the end of a beloved parade would be like asking for a natural disaster to blow through the park. It would not only kill good will for the APs but all regular paying guests as well and most likely hurt business.
WDW and DL are different beasts, comparing them doesn't work.
And everything, and I mean everything, Disney does will always be about money. No doubt about that.
