I said "financially, it's not a big deal". Losing that self-governing thing isn't going to hit Disney's bottom line all that hard. Certainly not as hard as trying to move DisneyWorld would. THAT would take the whole company under. In terms of the negative publicity and what it's doing to their stock prices and the goodwill of their shareholders, this fight with Florida is a problem for Disney, at least in the short term.
If Florida had decided to review and potentially end these sorts of agreements for some other reason, without all the cultural strife in the media, it would ultimately have been an annoyance to Disney that they just absorbed and moved on from. Anyone who thinks that Disney can just flip the bird to Florida with impunity and continue trying to bully them is badly misunderstanding the situation. Whatever the shareholders of Disney do or don't think about the LGBT community and public education, they are invested in that company for money, not for cultural warfare, and they're going to be pissed at having their money squandered like this.
