1) "owe" - as in some kind of contractual obligation? were I a ticket-holder or Mr. Crockford, I would speak of being owed something, but I think you are using a strange word for a privately-presented public-conference that has insinuated quite a LOT, actually, by such a provocative statement. This private organization presenting this public conference can, of course, refuse to divulge anything it wishes to. The stench, however, only grows more fetid, like a used diaper hidden under the bed.

We are currently led to believe that the early invitation to speak issued to Mr. Crockford has been rescinded due to some horrible and recent behavior on the part of Mr. Crockford, sufficient to warrant taking said secret allegations seriously enough to both rescind the invitation AND maintain the secrecy of both the allegations AND the identities of the accusors.

While we, the rubber-necking public, are not "owed" any explanation, it's not a reasonable position to not provide one.

The pastebin conversation suffices, meanwhile to show us, the rubber-necking public, the paucity and weakness of evidence being used to dis-invite Mr. Crockford.

This is seriously some stupid shit.

It's not advancing humanity at all, and it's not EVEN worthy of the label "Social Justice Warrior" as it's more American cultural colonialism, forcing the world at large to behave like a stupid American television series of 30-minute-episodic-duration, often set in a domestic kitchenette... but I digress...

The actual Social Justice Warriors are concerned about real issues.
