Well I know full well that Nvidia send out review guides for their GPUs. I've seen them.
That's why they all run the same games etc, and are usually missing anything that favours AMD (not that there's an awful lot of that, mind) but yeah, it's definitely a case of "Do what we say, not what you want".
AMD also sends their own "reviewers guides", it is standard practice to ensure that developers show the strong points of products. From there it is up to reviewers to cover everything else from there.
The point is that you use all the tests that all companies want to see used, plus a few tests of your own, then you have a fairly balanced review that covers the strong points and weak points of a product.
You would be surprised how much of a PC novice a lot of reviewers are, some need the guide to make a half decent review. Most don't even know how changes to CPU voltages other than V-Core affect overclocking and system longevity.
To put is simply, "reviewers guides" are not the evil thing that clickbait sites and reddit would want you to believe.
