No, I was very thorough: I saw every comment and pulled out the obscene, aggressive, offensive acrostic embedded in months of harassing tagging of the target of that acrostic because that recent pattern of behavior overshadows everything else. There's no excuse for that entry no matter how frustrated they get.

Vercel owes them nothing—and the specific employee OP chose as a target owes them even less—and this entitled behavior is a long-standing plague on open source that needs to be called out and soundly condemned. If they need the feature so desperately they can add it themselves (Vercel already said it's something they want to implement!) or switch frameworks.
