Because Democrats, being (at the moment, and relatively speaking) the party of government actually functioning according to laws, are extremely unlikely to do this in the other direction. The two sides are not the same. It is not possible to be the party aligned with institutions, rule of law, and predictability, while also using the power of government arbitrarily and vindictively. On the other hand, it's entirely possible to use the power of government arbitrarily when you're the party of greed and corruption. So "Republican-aligned companies" don't have to be nearly as worried, and otherwise-neutral companies will become Republican-aligned out of self-preservation, because one side is going to punish them for disobedience (legally or illegally) and the other side isn't.

I worry that they don't expect to leave power because they're acting like they will never be held accountable.

None of them really believe our economic or political systems will be recognizable by 2029. Everyone's playing for position in the short takeoff.
