Also everyone's personal set of shit companies doesn't overlap, so it's very easy for no one to get hired fairly quickly, and sometimes people chose the unpopular place out of necessity vs. choice at the time.
A large amount of employees people want to hire have probably worked at a company that people didn't like at one time or another. It's pretty easy to think of a set of nerds who don't like that you've worked at any one of google, microsoft, apple, amazon, facebook, netflix, robinhood, stripe, hospital system, any bank/finance/fintech, government, etc. Pretty much the only companies left are the ones that are not relevant enough to do anything to the world that would lead to someone being a hater in the first place.
I am still not hiring ex-Palantir people anytime soon, though. It would creep me out to look at them.
Without MS Office, the USG probably could not make the scale of the wars that they do.
