We don't really know enough facts to judge T. Fury. By definition of his life's work thus far he is a fighter. He beat one of the very best ever. He still remains the most skilled super heavyweight in existence.
The social and cultural planners,the designers, engineers, and constructors of Britain, have been hunting him over words he expressed about the culture and society they are building. To retaliate, "they" attempted to characterize him as a drug cheat, and have temporarily withdrawn his license to work inside that particular society. T. Fury does not need to put himself under their authority; T. Fury can work somewhere else about the world. I presume T. Fury knows this but has chosen to play along with these imagined "authorities" because it will be to his benefit sometime in the future.
I see T.Fury as much clever than most do. I presume he has voluntarily withdrawn from boxing, and withdrawn from the social authorities, to remove their attacks and control over his business. I presume he will return, better than before, and box the day lights out of their chosen dark hero, a PED boiled klutz known as " Anthony Joshua".
