I don't think it's reasonable that the organizer not be held accountable. From this article:

> By the time I’d received notice of the event unfolding on the evening of 2016-09-01, the decision was already made by the main organzier, swiftly and without discussion.

> And in a moment of confusion, a poor decision was made to remove Douglas Crockford as a speaker, by the main organizer.

Just because the organizer was put in a tough position doesn't mean they shouldn't be held accountable for making the wrong decision.
