Doesn't seem to me that OzR 'directed' anything. They were offered exclusivity as the quid pro quo for paying a lot more money in sponsorship:
Later, the organisers needed more money. Other industry groups were approached, multiple times, but declined to support the airshow (and we're not talking $500 for a table). They asked us again for more money with an offer of exclusivity, which we accepted.
A tip for the future, OzR: In matters commercial, no kind act goes unpunished.
