"Celebrate the opportunity to collect unemployment?" Spoken like somebody who's never done so. Even if your erstwhile employer doesn't contest the claim, the whole process is a clusterfuck at the best of times - to say nothing of these times - and typically yields somewhere around minimum wage, often approaching it from below. If you have a solid savings base, it's a trivial amount. If you don't, it's better than nothing, but usually not enough to make a meaningful difference. And that's if whoever fired you in the first place doesn't make a fight of getting it at all.

I agree that Twitter cancel culture is well out of hand; in fact, I'll go further still and say that the behavior is often not meaningfully distinguishable from 4chan brigading of old. But there should still be a better option for dealing with unreasonable but not actively criminal bosses than getting fired anyway, with the chance of a bare minimum consolation prize.
