What does SpaceX have to do with the Musk/Trump spat? Shouldn't those SpaceX contracts be based on how well the country is served by them and at what price. Trump needs to take his lumps on his BBB. That bill is full of pork for billionaires and cuts funding for poor folks. It should come as no surprise that people don't like it.
Well, SpaceX is owned by Musk. Therefore Trump, if seeking to hurt Musk, could attempt to hurt SpaceX.
The ends justify the means. The country's best interests are collateral damage, the benefit that SpaceX offers the country is not relevant to Trump's ego/feelings having been hurt.
