It's pretty true that the pay trumps them all. But Google is generally pretty good at matching Facebook's offer. So when choosing between FB and Google, or any of FAANG, the pay is usually less of a concern. So being considered "not inspiring" and "evil" is definitively not helping FB to close on the candidates.
FAANG's hiring processes are so arbitrary and non-repeatable that it's entirely possible (even likely, I suspect) for a person to have offers from just one of these. Other than Amazon, an offer from these companies is practically a lottery ticket.
