The final one is about a YouTube animator JoCat who was as far as I understand pretty beloved and charming.

I may not be up to date on events but while streaming he improved a gebderbent version of boys by Lizzo and people liked it so he made a full animation for it.

A small but loud number of people, primarily from outside his community considered the swapping of the genders and/or the platforming of Lizzo to be misogynistic and gave him enough hate that he permanently stepped away from content creation.

I have no idea if anything else has happened since but to my knowledge that's the event that made him "cancelled". Imo it's different to being cancelled because most people are on his side and are supporting him, and everything I've seen about this news takes that stance. Him suffering abuse from a few niche corners of the internet and quitting the platforms is not the same as the internet's collective consciousness turning against him. Metaphorically, he which his workplace due to bullying by people who foybd something he did obscene, he didn't get fired for it.
