Do those affiliate codes support the original reviewer guy, or just the operator of the website (if they are different people)?

Does it matter? As someone that has hunted for cables reviewed by Benson I really wish I had known about this website. They are both providing a service.

It's definitely useful. I just wouldn't want Benson's review work to become unsustainable because of lack of funds, jealousy, or whatever.

He works on the Pixel team at Google and orders the cables through the company for testing.
