I'm not so sure that detracts from their reputability, does Rtings seem less reputable because affiliate revenue is part of their income?
I still trust Rtings and love the website, but yeah it's totally possible that at some point they leave out a product because no revenue. I think the hit to their rep would be too big so they wouldn't, but it's always possible.
I think you’re truing to split hairs on what “reputable” means maybe?
