I have absolutely no sympathy for Musk but the president--any president--shouldnt be able to do this.
I am not surprised that Biden didn't cancel all SpaceX contracts for political reasons, neither are most rational people.
Being an adult child has moral and ethical consequences.
Behaviours and emotions that are totally legit and tolerated in a child are no longer so in an adult.
An adult that has all the privileges and freedoms of adulthood over childhood, like the ability to vote, drink, drive and hold an office, also has to abide by the moral obligations of being an adult.
but that's a problem, isn't it?
That's on us. Why on earth did we stop expecting adult behaviour from ultra-rich people?
