Also, based on your comment history, I'm not necessarily doubting your truthfulness but you do seem to be pushing a focussed agenda in your comments.
Sure, the Russian government will welcome any form of friction within the US or EU, and probably will not hesitate to create it when they see a chance. But there is no need for any Russian propaganda to seed such doubts, because the US and EU do a marvellous job just on their own there.
Also, anyone who doesn't question the validity of something, once there appears to be any discrepancy (even if that turns out to be a false alarm), is either a blind believer or an idiot. The only agenda that I "push" is to indeed question everything. After having witnessed first hand what some US and EU based "humanitarian" organization do in other parts of the world, I think I have very good reasons to be extremely sceptical about any expansion of their "freedom and democracy".
2nd: WADA might be situated in Canada, but that will not prevent the US from trying to influence (or even infiltrate) the organization. Either way, WADA has already received its share of criticism. I don't know enough to judge if that's information warfare against WADA, or if the organization has indeed become a US puppet as some do claim.
3rd: anyone who has been following this whole thing for a while, should also have noticed that some professional athletes from other countries appear to be getting an easier treatment than Russian ones. Could just be framing in the media, but could also be a real thing. I could honestly not tell. Still, when it comes to counting actual verified accounts of deliberate misinformation, I think that the US media is currently a lot more high on propaganda than Russian media (though neither are innocent, obviously).
