I think it's more 'Anthony Joshua privilege' than anything else. Joshua is currently rated #1 by the WBO. Usyk didn't deliver that big 3 percent cut against Dubois that the WBO was used to with Joshua. That's several million less in sanctioning fee money coming in this year for the WBO. Joshua and Anderson could now fight for a vacant WBO belt should the WBO get a wild hair. Or at least a final eliminator.
Meh, Arum is just leveraging his connection to Warren with the WBO. It corrupt, but it's nothing new for them August 2020 , Daniel Dubois was WBO #3 [url]https://www.standard.co.uk/sport/boxing/heavyweight-boxing-rankings-top-10-wbc-wba-ibf-and-wbo-fighters-and-world-champions-a4412436.html[/url]
These organizations are not beholden to reason or fairness or logic (exceptions obviously, see Rocchigiani, Graciano). So do not expect any of the above until someone cleans them up or holds them accountable
