TBH, with work I've usually been able to find whatever video I'm looking for...
Lucky you, I haven't. I took a peek today at my only fanfest which is Keiji's, and the vast majority of non-show, non-Japanese events have been taken down. There are a few lurking around, but most GP, Challengers, Universiade, 4CC, Worlds, are simply gone, and when I search online, not even sites like Dailymotion or bilibili are of much help. I was searching in kanji, too.
Some folks mentioned new video re-uploads by youtubers, but I haven't seen a single one, so I wonder what I am missing.
The cause of the problem seems obvious to me, the powers that be were only thinking of stolen music and movies, not about the implications this is going to have for the rest of the videos. The difference that movies/music are typically available for downloading for a fee, or sold in stores, whereas the sports stuff disappears into the company's archives, never to be used again, seems to escpae them, or they simply don't care.
If there's a petition to change this silly regulation for sports videos, I'd be happy to sign.
I wonder if the ISU will just sit back and do nothing... I wouldn't be surprised.
