You are correct
I don't know a lot about the airshow business, but I would expect that the organisers might not want to pay, if you don't display.
Safety comes well before displaying when the conditions are not suitable. Display pilots would have a horizontal routine should the weather preclude a "normal" routine and if the weather was unsuitable for that a fly past or nothing at all. They were my plans for displaying.
As for
However, in this case we seem to be overlooking the bit where some of the people charged with running the show, failed to do their agreed bit to provide a safe venue.
I think the "event" occurred outside the display area.
