They could (or should) have been more transparent with communicating their reasoning, but again: Anyone who has ever organized any decently sized event knows that in the end the buck will stop with whoever has to do the actual work. And if you ask me (you probably didn't), giving organizers that power and trust is generally reasonable. They have the best insight, they have to carry the consequences if it does not work out, etc.
Of course that trust can be lost and a community can decide to let other people organize their event next time. But the way I see it those made responsible for an event should be able to shape that event.
