I didn't read the rest of this thread, but as has been pointed out earlier, this is not exactly the case. Disney World doesn't "require" unvaxed to be masked. Rather, they "expect" it. This is an important distinction because Disneyland uses the "required" language for masks for indoor settings for the unvaxed. If the mask policies for the unvaxed were the same for both parks, they would have the same language.
Here's how Disney World phrases their current mask policy:
"Face coverings are optional for fully vaccinated Guests in both outdoor and indoor locations. We expect Guests who are not fully vaccinated to continue wearing face coverings in all indoor locations, including indoor attractions and theaters. Face coverings are still required by all Guests (ages 2 and up) on Disney buses and monorails."
