YouTube may indeed be the problem but I don't see how it's a fair use issue. This is a case where the rights of one copyright holder in their broadcast, Fujitv, are being extended to block access to the copyrighted works (broadcasts by other networks) of others. Effectively they're taking away the rights if CBC, NBC, etc. over their own content. Unless there's something we don't know - for example, perhaps Fujitv is providing the live feed used by CBC, NBC, etc. - that's pretty outrageous.
YouTube is still the problem. They don't have to agree to take down the videos on an alleged copyright holder's say-so. The complaints should be directed to them.
I thought I read somewhere today that the CBC actually allowed free viewings of the newer videos because they were record breaking skates? Maybe the CBC made some exceptions this weekend, because I was able to watch those same vids too from the CBC and they are usually geoblocked for me.It is interesting and complicated. For example the new CBC videos (FS Chan and Hanyu, FD Virtue/Moir, FS Osmond and Daleman) are not geo-blocked in Germany. The first CBC video (Yuzuru Hanyu practises at 2017 World Figure Skating Championships) is in Germany not available.
the great majority of Tv1dance videos are restored
I guess they just have a temporary block on the videos until they are aired on TV in Japan?
