They are all shills to a degree, some worse than others, on a GN live o/c stream nvidia rang him during the stream and he had partners contacting him as well, you can tell when watching it he absolutely loves been part of that circle, having inside access and so forth, and it isnt just GN, they all do.
Every so often, I see a reviewer having been cut off from a manufacturer for whatever reason, then buy a product to review and give it a terrible review, I have seen this enough times for it to be mere coincidence. (smartphones, and other types of products not just PC). I call it "revenge review".
Jay for sure has a nice relationship with EVGA which I expect makes him a poor bet to trust on reviewing anything EVGA, and he seems to be pro Nvidia in general.
Industry needs someone to come into it reviewing just retail parts, not subject to review guides and so forth, with no connection to the industry.
