...What WSFS is, what Worldcons are, all carefully written in service of getting people on the same page, how it boils down to what's basic:
There is no they. "They" don't exist, just fans.
WSFS doesn't exist either. "WSFS" and related are registered service marks. Protecting them requires year round vigilance: a handful of fans volunteer to do it. That's it.
The first World Science Fiction Convention was in 1939: a bunch of fans decided fans should have a time and place to meet each other. 85 years later and it's the same. Fans volunteer so fans can get together. Anything needs to be decided, fans make the decision.
I have a couple of issues with this.
First, what you are describing is very literally "they". We understand that there is less formal/strict leadership, which means that there is no one person in charge. Just groups of people, just a bunch of fans. Which means that the organization is, de facto, "they". That's the word we use in English to cover exactly the situation you are describing.
Second, we have names. Dave McCarty, Diane Lacey, Chris Barkley, Jason Sanford, just to start. We have emails. You can't claim there's just some amorphous blob of anonymous people when we literally have the correspondence of some of the individuals responsible, discussing the choices they made and actions they personally took. We know the list isn't complete. We know these people weren't responsible for everything. We know there were others involved at multiple levels. But the fact that there are other people involved doesn't absolve any of these individuals of the roles they played.
Third, this is not a solution. It offers no hope, no direction for change. It does not help. Frankly, this is just more minimizing.
Finally, the situation you are describing is what I meant in my last post when I said these were systematic issues that will require systematic responses. If there was a single person in charge, we could point to that person, or to a specific failure. The fact that the organization is just "a bunch of fans" is why the entire process needs to be re-examined if you want to stop this from happening again. But if you try to hide behind the anonymity of "just fans", if you want to just pretend this was a "one off", it guarantees the situation (or a worse one) will eventually happen again.
