In theory, if we had truly open marketplaces that offered equal monetization of all links to all similar products in the same category regardless of the price offered to the consumer, sure.

In practice, that is never the case. At best you're getting reviews that only compare products available in the same marketplace (say, for example, all the table saws you can buy on Amazon). At worst, you're getting reviews from vendors who offer the highest payout.

Also, a heck of a lot of consumer products are absolute garbage. (IMHO, most of them, but others may feel differently.) Who is going to write an honest, scathing review of a product and then monetize the link to it? Why even bother?
