I would be pissed if I was promised a chance to fight in front of 60,000 of my countrymen, then told that it's not going to happen because my boss doesn't know how to plan properly.
How do you know it was the UFCs fault? Dana White has been planning events for years now and has not had this happen. How do you know the UN did not schedule after the UFC did?
AS has a right to be upset and disappointed, but why are they having to work hard to convince him to fight elsewhere?
