The alphabet bodies are corrupt and always make stuff up as they go along. Fury last defended the belt in April of last year. That is a shorter gap than: The WBA (before Usyk beat Dubou, it had been nearly 5 years since AJ defended against WBA mandatory Povetkin). The IBF (they have not had a mandatory challenger since Pulev if memory serves, which is coming on 3 years). The WBO (Usyk was their last mandator and he won that belt more than 2 years ago). While I do understand the point you are making, I'm not a fan of boxers being stripped as a general rule, especially with the corrupt mess of alphabet soup and their pay-to-play schemes.
