FIS is just following IOC recommendations and it applies for all disciplines so I doubt Sweden and Norway are behind this, and they are certainly not the only NSF against Russia competing.
FIS is not an independent organization, and as Mayo perfectly put it, COOP has a big influence in FIS right now, and FIS doesn’t want to lose their biggest sponsor.
Speaking of the IOC, did you read what Bach said? Yikes. He sounds like a very old man who says one thing in one sentence and something that totally contradicts that statement several sentences later. I wonder if he actually realizes what he’s saying.
