You are confusing pointing out that people are morally responsible for the their actions with suggesting "that someone should leave their job on ideological grounds".

I get that you (and most of them) want to cash the checks without feeling responsible. Tough. People make the choice to work there, and they make the choice every day to keep working there. Other people get to make choices too, including about how they think about, describe, and treat people who profit from harming others.

Freedom of speech and freedom of action does not include freedom from consequences. Your freedom, or that of people making bank at Meta, is not more important than anybody else's freedom.
