I think you're uneasy because you're assuming the accusation of cheating has to do with the outcome of Hans's games but I don't believe that's the criterion Magnus is using. Magnus has been beaten many times before, but that doesn't automatically cause him to suspect his opponent of cheating. Magnus's suspicions arise from a sum of many different factors some of which he mentioned in this tweet and some of which he clearly can't talk about. If we judge people based on their past actions, their suspicious behaviour during the game or during the post-game analysis then it doesn't preclude the advancement of a legitimate genius player.
