What are the advantages Disney has regarding Reedy Creek compared to other businesses in Florida?

I’ve seen quotes of DeSantis stating that it isn’t fair that a business should have an advantage over another due to a special district designation.

What exactly are the specifics of the unfair advantage?

I live in The Villages (TV) in Florida, which is a special district, and for the life of me I can’t find much difference between where I live and Disney, except the year TV special district was created.

Obviously, some of this is just politics, but I’m interested in any possible valid arguments. Also, from a legal standpoint can Disney argue other special districts need to be dismantled if Reedy Creek is taken away?
