People thinking the UFC needs Conor and Conor doesn't need the UFC are idiots.
Viacom ain't spending the same money on him. If he ever walks over money, the show still goes on. He goes to the minors. If I was Eddie I'd force both their hands and make it clear; he's holding the cards. It's the belt he has that Conor and the UFC want. It's the legitimacy beating him brings they're paying for.
He should make it easy: if Conor wants to fight him, the price is millions. Otherwise pay him what he normally makes and give him a guy actually at LW. He's not refusing anything, he's telling them how much his legitimacy is worth right now.
