Jay you mean? I replied to a comment, not the video, and the comment only said "backup os".
Still, I admittedly did not watch the video because I've stopped watching that guy years ago. He's one of the least knowledgeable "techtubers" I know. The only thing he was good at was custom watercooling stuff, but I don't know if he still does that stuff.
Lastly, while it does suck to not be able to play a game due to anticheat, the best way to solve that issue is to not play those games. The devs will propmtly find a way to make an anticheat that works on linux too if their playerbase demands it.
