They dont like uploading performances on Youtube because NHK official site has all of them with good quality.

No, I understand that NHK won't allow the videos being uploaded due to copyright laws. What I meant was I don't understand why the poster would say that she would "stop being a fan of Japanese ladies and cheer on everybody but the Japanese" because NHK is blocking the videos. No correlation there.
Oh, but that's her prerogative, so, oh well. I just don't get it.
