I personally wouldn’t hold it against someone for working at FB. Life and people are way more complicated (or not complicated, for that matter) than what you’ve reduced it down to. For one thing, consider that just because you exclude people who worked at FAANG, you’re not actually accounting for all the other thousand ways people can behave immorally or amorally. Screening out FAANG employees doesn’t actually get you very far in this regard. So it just looks like you’re harping on this one thing. Do you screen candidates who you think associate with politics you think are immoral? Or who have worked at tobacco companies? Etc.

That said I appreciate your attitude here. These companies are civilizationally damaging. It’s good to keep repeating that. I’m just not sure your approach makes sense.
