Long time and big name game theorist calls it quits in this video
Here's an article about it. He had put in 13 years to theorizing. His wife and he knew it would be coming. Tom Scott finished his last regular video, and it felt like the right time.
Another article. The late nights and constant work was grinding on him. He wants to play games and not look at Loooorrreee
Fans say goodbye to him. The different channels will be taken over by others, while Mat oversees.
I'm not very familiar with him either except for the "But that's just a theory!" memes, but bold of you to assume he is not simpatico with the blue haired weirdos himself. People did the same thing with Linus Tech Tips and pretended he had no choice but to let his friend dress like a woman on the channel if he didn't want to get canceled, when the reality is he supports trooning out. He is at best a lefty normie and this guy most likely is too.
