I don't have enough knowledge about the fire department to have an opinion on that part of this question. If the State of Florida and the new RCID board arranged for the Orange County Fire Department to take over the operations of the RCFD, along with giving the county RCFD's budget, I would find this line of inquiry more interesting. But the fire department is obviously irrelevant to the actions of the governors office, which is why more direct methods of addressing fire department issues were not pursued.
Government primarily serves the public within its jurisdiction. The RCID's public is Walt Disney World and like three other people.
Governments can serve the public in a broader sense than that. But using that metric, RCID rarely did anything that wasn't in the interest of the state of Florida, or Central Florida in general. When I read Married to the Mouse by Rick Foglesong, I was surprised at how little Disney abused the power of the RCID.
Yes, RCID may have approved building permits more quickly than Orange County would. But crucially, the longer review time at Orange County is not because of greater scrutiny or a higher standard. Instead, that longer review time at Orange County comes from a lower level of staffing VS demand, unclear directives from elected officials, and a generally lower quality of management within the Orange County Government permitting office.
