The contract only applies to taxi service. It's got nothing to do with ride sharing and Disney has embraced Uber, even offering ride sharing locations for pick-ups and drop offs at the parks. You obviously have some kind of axe to grind about it.
Here's an article that specifically quotes the ways in which Disney has gone out of its way to embrace the technology:
"Disney said it has made some other changes aimed at Uber drivers over the past year, including working with the company to designate specific pickup and drop-off areas.
Last fall, a Disney spokeswoman said, the resort lifted parking fees that drivers paid to pass through the theme park gates...
Disney and Uber didn't provide numbers of customers using the service at the resort — though Correoso said Orlando usage 'has grown significantly.'"
