Would it be illegal for Disney to encourage or indirectly fund a hit piece on PewDiePie? It's very likely the OP here is right: YouTubers are imploding. Disney probably is the first to see that(they acquired Maker Studios a year or so ago) and needed to offload a massive failing asset.
The anti-semitism problem is a very specific angle to take particularly related to Disney and PewDiePie. Someone clearly combed his trove of videos and found every single Nazi reference; seem like a stretch to begin with. Idk theories.
