You are missing everything. Actually taxes and government spending these days are now associated with socialism and communism by the crazy party, so I'd say it's pretty damn polarizing.
Regardless, Musk pretends to be above the fray when it comes to politics but he has shown he is more than willing to talk about it when it comes to his money. If you want to be above the fray then do it, otherwise sometimes you got to talk about the tough subjects. Why should he get special treatment on tough subjects when he is lying about his stance on opining on politics?
There is no way around it, he is a hypocritical douchebag on these subjects. But keep on carrying his water for whatever reason.
