The bolded is not a fact, it is what has been claimed. A Sky doctor reported to the UCI doctor that Froome was sick enough to require an emergency TUE for the drug in question. WADA has confirmed this. This does not mean Froome was actually sick, it just means that's what the Sky doctor told the UCI doctor. Nothing like that has ever been underhanded before, right?
One can choose to believe that Sky took an acutely ill rider, their TdF leader and pumped him full of 'roids to compete and easily win Romandie. One could also choose to believe that's a load of codswallop and they got him a TUE for a drug he was using in training. One could also choose to believe he was "too sick" for LBL, or one could choose to believe they kept him out for other reasons.
There are no facts WRT Froome actually being sick other than that's what Sky has claimed. The claim is a fact, the actual sickness is a matter of belief one way or another.
