William Golden and Jason Orendorff seem to be the only organizers in this discussion, and neither of them says anything more than "he was uninvited because other attendees and speakers did not feel comfortable attending/speaking with him there". There's some speculation and links to a video where he references genitalia, but none of that appears to be acknowledged by the organizers.

I don't see anything in this chat log that changes anything.

18th line, "there is more context around it on twitter but that’s the basic gist".

So, again, referencing the tweets & subjects preceding their announcement as context aren't unreasonable as Golden says there's more context on Twitter. Emily Rose, notably, unleashed a series of tweets at them until they capitulated. It's still not the official word you're seeking, but to ignore it seems willfully dismissive.

Moreover, in what manner would a direct affirmation or counterpoint by the Nodevember organizers be advantageous to them? I'm not trying to be conspiratorial about it; being quiet and vague is the far more diplomatic path. It's not in Nodevember's interests to be precise with the particularities of the disinvitation, nor are we, as outsiders, owed any sort of particular explaination. But neither were any details provided to Crockford for him to ameliorate. "It is a mystery to me too." per https://paulstraw.svbtle.com/crockford

Reading that I feel sorry for HermitPy, it would seem they're trying to please everyone and getting burned :(
