Technically all they're doing is sticking to their "rules" I suppose. Filip was 1, Dubois dusted Filip to take interim. But we live in a boxing world of polar opposites with bodies. When they are doing this, the wbc allows champions to hibernate on their belt. The biggest problem I've had with the ibf is the fact that they keep "vacant" ranked at 1 or 2 and sometime both in every single division. Save for 112 and oddly 168. It's a built-in arbitrary pass to run guys up on a whim pretty much as they wish. And tbh I think if Usyk wasn't Usyk in name and maybe lack of crossover marketability, they wouldn't turn the screws on Usyk in the background. He's not some glory boy fawning over them at every turn. He's the literal definition of the fighter makes the belt not vice versa. They'd also see the sea change with Filip losing and the possibility of Aj/Joshua rematches aka read the room and make exceptions. But that's looking too far ahead and Dubois v AJ is what's happening now for them. Turki may wag his finger but let's not pretend having a championship tag and belt on that fight tickles him juuust fine. Personally I've reached the point where undisputed is a little overrated. It in its own way gives more credence to the trinkets now. We've seen champions literally left "unified" up to the point of entering a ring...and then instantly considered stripped. For no other reason than marketing and selling tag lines on the banners as in Charlo v Canelo.
