When the market turns (and it will regardless of how loudly AI cheerleaders proclaim otherwise), I just hope engineers as a whole remember this despicable behaviour by Zuckerberg.
The silver lining(If you can call it that) of the latest slump in tech employment is that it has laid bare the reality of the tech oligarchs. Someone should set up a website to catalog this behaviour so that these corporations and leaders can't easily sweep this under the rug in the future.
