Not really - the inclusion of that absolutely arbitrary, absurd clause, shows that they know that eventually this will be overturned legally, and it was just about making a statement. As others have said, they just hope that DeSantis time as governor is coming to a close as he moves to the national stage, but given his massive popularity in Florida, the thought that whomever follows him isn't going to continue what he started is just delusional.
The more you think about it, the more stupid and silly it was to include, not to mention the morbidity of it, invoking the deaths of people who are currently infants. I can't stand the Spare, his repulsive wife, and their constant disgusting behavior, but in this case - they would totally be justified in being outraged that Disney is creating contracts where the deaths of their children are used as clauses in what basically amounts to joke.
