I'm referring to the section header in this article. Youtubers are not a truly hegemonic group, but there's a set of ideas and narratives that pervade the group as a whole that different subsets buy into, and push, and that's one that exists in the overall sphere of people who discuss the use of hardware for gaming.
Well, I can't speak for all youtubers, but I do watch most GN and LTT videos and the complaints are legitimate, nor are they random jabronis yolo'ing hardware installations.
