I get and agree with the idea that open source is communal, but Azer didn’t remove source from the community.
He did disrupt some node devs and that is unpleasant. He did it in a way that a) exposes a vulnerability in the npm architecture, and b) lashes out at the people he believes are oppressing him.
To me Azer seems like the oppressed one, but I accept that is up for debate.
Given the source is and always was out there, there is no argument that it was removed from the community. If you agree he was oppressed, then I’d hope you see this as a valid form of protest, as it brings clearly to light what was going on.
