The thing is Russia has been doing this stuff for ages. A lot of these structures and people go back to Soviet times. And of course many Soviet Bloc doping specialists went on to commercially provide their services elsewhere in the 90s and 00s - something rarely discussed at the time or now. When Australia went from a sporting nobody to a contender just in time for the 2000 Olympics and Britain did the same for 2012, it was pretty obvious that these were driven efforts to justify the expense of hosting the events and to boost national morale with a good performance at the games. Neither was much scrutinized in the West.
What I am saying is that doping only ever seems to become a major issue for the media and so forth when the country doing it is a geopolitical adversary of the West. When Russia was courted as a new ally and eventual NATO and EU member noone gave a damn about their doping, it only became a matter of urgency when they instead decided to go in a different direction. Its just a weapon used vs Russia in this new crypto Cold War v2.0.
