A timeline of events:
Disney: Wields their power to try to influence the vote of a political bill
Florida Government: If it is a political battle you're after, then let's proceed. (Removes special tax exmpt status)
Disney: What!?!? You can't do that!!! We're just a a family entertainment company!!!
The way I see it, if Disney wants to become a political lobby, then they are opening themselves up to political backlash. I very much disagree with politcally targeting businesses and corporations, but it gets a lot murkier when the businesses and corporations are interjecting themselves into local political processes.
