You apparently can be this stupid.
Anyway, Dana deserves the assist by being Conor's biggest ball washer and cheerleader on that clown show world tour where he basically chauffeured McGregor around the world so he could smack talk Jose in a language he didn't speak or understand fluently. Aldo tried to take all those words out on him in one punch, mistakenly, ate a huge punch, got finished. All time bad outcome.
There was zero chance Conor would ever duplicate the performance, so there was no reason to give Jose a rematch. When you realize the UFC refused to let Aldo be double champ in a fight against Pettis and didn't care for him due to his injury history and comments on pay, it makes sense entirely why they avoided it, only offering it up to him on short notice, out of camp, a weight class up.
Shit happens. Life moves on.
