Brief summary: Suede, a YouTuber who's been making a living reviewing every episode of Pokémon from the beginning, is about to get his channel deleted thanks to a legal technique used by the Japanese production company, ShoPro, that bypasses all protections YouTube has in place and has no way of being stopped. This sets a precedent, as all prior takedowns of anime footage on YouTube have used YouTube's own copyright claim system, which allows a defense under U.S. Fair Use law.
