This is my take. Once their bottom line starts fluctuating, they’ll simply find a new loophole to exploit so money keeps flowing, while slightly adjusting their fleet of yachts to a safer distance.

There’s no allegiance to anything. US is just the most convenient place to generate wealth right now.

Maybe, maybe not. This has turned out differently before. Here’s a tidbit from Homage to Catalonia (emphasis added):

But there were several points that escaped general notice. To begin with, Franco was not strictly comparable with Hitler or Mussolini. His rising was a military mutiny backed up by the aristocracy and the Church, and in the main, especially at the beginning, it was an attempt not so much to impose Fascism as to restore feudalism.This meant that Franco had against him not only the working class but also various sections of the liberal bourgeoisie—the very people who are the supporters of Fascism when it appears in a more modern form.

It’ll come down on if they like authoritarian control better than they like money. They’re getting burned on the money part, and there’s no reason to think Trump’s policies will make it any better in the long run.

But don’t count on them either way. They’ll still enact policies that are good for billionaires, not us.
