States provide and remove privileges, benefits and incentives from companies because they agree/disagree with them all the time. Government, after all, picks winners and losers, and Disney receiving a benefit is a de facto punishment against its competitors. This benefit/privilege may have been wise when the land was undeveloped, but today it's a lot harder to justify.
I previously tried to provide some examples of CA removing benefits and privileges from companies/people they disagree with, but I seemed to have run into a word filter and the post was filtered.
Regardless, Florida is perfectly within its right to elect representatives and leaders that will remove privileges from companies when the voters don't like what they are doing. It's no different from government creating a benefit for solar panel makers or punishing an oil company. They did not try to place Disney below any other company, only remove some privileges they no longer want to offer a company that goes against the values of their voters.
