It don’t think it has any relationship to the Japanese tivi station. It might have to do with the music license. If I remember correctly, the music he uses are quite modern from a movie which is banned in China.
Also, Japanese tivi has blocked many of Hanyu’s videos on YouTube. Half of his videos last season on YouTube are gone. Sometimes YouTube works weird. They haven’t blocked you doesn’t mean they won’t. Their algorithm hasn’t touched you yet.
As far as I know, this movie is not banned in China, it is also a collaboration of Chinese and Western movie production.
Also, what criticized in this movie is culture revolution, the Chinese government itself also criticized the fault of culture revolution ever since the economic reform lead by Xiaoping Deng. In the end of the movie, the dancer's parents were invited to Houston to unite with their son because of the open and more free political environment after Mao's death and the start of open China.
The music copyright could be a reason why Nathan's video is taken from internet. but that should apply only to FS not SP. But indeed, it is very diffcult to find the FS music track on internet, but it has nothing to do with its political orientation OR whether it has been banned in China or not, just purely a music copyright thing.
