Lots of misinformation and mixing apples with oranges - Froome's case is not TUE doping, he went over the salbutamol limit allowed without having a TUE, if he had been granted a TUE by a doctor there would have been no case. Same for many Norwegian skiers who (ab)use (of) medications within the legally allowed limit but if they go over that limit they risk disqualification not having been granted any TUE (see Sundby).
And of course Russians are persecuted by evil whites because they are brown, "it is known".
