No, he was a journo who had a huge impact on the industry. The guy was a pioneer of professional conduct and transparency in gaming journalism and he was incredibly brave and tenacious in exposing games that suffer from technical problems.
If you watch some of his video reviews, the first thing he does is he would often spend like 5 minutes going over all the technical option in the menu and detailing what they do and whether they actually work properly. He seemed like a madman the first time I saw it, but he kept at it regardless of the reactions and eventually developers actually started adding options that he demanded. Like, he's basically the sole reason why shooters have FOV sliders.
He was also a respected reviewer and promoted a lot of indie games to success and did some commentary and casting for Starcraft I think? But his biggest impact was exposing bullshit practices of game industry and losing him is awful, awful news for the gaming community.
