I don't know that I fully buy this either, at least not the anger part.
I can look back on all this with wry amusement nowadays but I remember it being pretty frustrating at the time.
It sort of felt like, well, either you knew what the impact of unpublishing all your packages would be and you did it anyway, which makes you kind of antisocial, or you didn't know what the impact would be but did it anyway, which makes you kind of a hothead. And in this latest piece Azer has admitted that he didn't understand what the impact would be so... y'know... I do wonder if anger was at least a small factor.
Regardless, it's pretty clear that npm bear a lot of the responsibility for what happened. It's also something that happened a very long time ago and, as I've already implied, is just a funny story nowadays, not something I can manage any ire towards Azer over.
