From essentially always. The Eastern Indies Company may be the first clear example. Ultra capitalists squeeze the State whenever they can preach that others should prevent the smallest subsidy

This could lead us to a complex discussion about ideology but I believe that Musk is rather an ultra capitalist (what we call ultra liberal in Europe) the repression of the State cares for shit, it only wants tax reduction and disappearance of regulations to the maximum. Trump is a more classic fascist, he wants repression and total control by the State (as long as he is the one who controls the State, obviously). The clash was inevitable, as I said before, reviewing the story will give you the answer

A fascist betraying the hyper-capitalist who supported him to defeat the left. If Musk knew more about history, he could have seen it coming.
