Disclosure: I used to work at one of Priscilla and Mark's charitable organizations, many years ago. I left for a number of reasons, chief among them was the realization that Facebook is not run in an ethical manner, and that it has a negative effect on its users.

Here in 2020, there should be absolutely nobody who's deluded about how Facebook does business and makes money. So, if you're a scientist or doctor and you're just now speaking up because something something Trump, that means you were fine taking dirty money, as long as it's not dirty in one particular way. I suggest you do what I did: either take Priscilla and Mark's money and keep quiet, or go work somewhere else.
