It looks a lot better on the resume to say "I quit in protest" than to say "I was fired because I refused to do my job".
Quitting in protest also makes better headlines than getting fired and it lets the person quitting set the narrative. "I quit because the administration was asking me to do something unethical or against the best interests of the American public" makes for good headlines, compared to "Trump admin fires head of the NSF" and then having to go on damage control justifying why you were fired and why it's a good thing actually.
