This Tech Won't Save Us podcast episode makes a very important point: any movement that does not have a structure and some form of leadership can easily be taken over by anyone willing and able to fill that kind of power vacuum.

Fediverse currently does not have a structure nor a form of leadership other than perhaps "whatever Mastodon is doing". That's problematic. I hope that we recognize this and do something to fix it, before that power vacuum gets filled by… someone we might not like.

I do see that the researchers involved in the OP link are Erin Kissane and Darius Kazemi. That's fantastic. They are truly fedi old guard, deeply engaged, very knowledgeable, and generally wonderful human beings.
