I too share your logic behind placing more trust in sites that go in-depth and review across all the brands, as opposed to focusing extra attention in only one

I too share your logic behind placing more trust in sites that go in-depth and review across all the brands, as opposed to focusing extra attention in only one or a couple. Regarding SEO blogs, I have seen a lot of "review rewrite" jobs posted on a freelancing site, indicating there is a market for this kind of devaluing behavior (worse than not adding value, this actually is a net-negative on society, where costs are externalized)
