Mostly because he is a YouTube entertainer, and not necessarily an tech expert. He got some shitstorm a while ago because of the bad treatment of some of his staff, and other YouTubers called him out because his benchmarks where wrong multiple times, but he would never revisit and correct them. Some staff members said this was impossible for them to to accurate testing and reviews because of the high pressure to churn out new videos.

Personally I get the vibe that he is nice and entertaining in front of the camera, but might be a less chill person as your boss.
