It is because the Dawg is African.
A not exhaustive peruse of this section will make anyone realize that as a minimum riders of the following nations have been under suspicions if not outright accusations : England,Ireland, Portugal,Spain,Luxembourg,Belgium, Netherlands,Denmark,Norway,Kazakhstan,Russia,Slovakia,Slovenia, Germany,USA,Australia,Colombia,Argentina and I think I am way short.
The number of pages a rider gets here depend on 2 factors . 1) How successful the rider has been recently. 2) How outrageous their "transformation" has been when compared to their previous performances. Sometimes 1 and 2 are present at the same time and those are the most popular topics. It 's not surprise that people like Froome will get a way bigger thread than Quintana. This is not a geopolitical Machiavellian calculation.
It also depends on wheter the majority accepts the rider in question is doping or not. For some it would be ”anglophobia” to not accept Froome and whatever british that turned a leg around some pedals suddenly turning up as the best riders ever.
For some it was ”anti-english” or ”racism” not cheering on England in the euros.
