I think that some companies have already caught on. I've seen suspicious recommendation patterns on Reddit before, where one product will be relentlessly mentioned, to the point where a naive searcher would think it's the "clear choice". But this could also be astroturfing.

For example, yesterday I was looking for a good toaster oven. The _only_ brand that gets recommended consistently is Breville, on multiple different subreddits. However, there is nothing that makes me believe their product is any better than the competitions. Mass produced in china out of cheap materials, lots of reviews stating that they break once the warranty is up, etc etc. All of the Reddit comments are also very simple. Doing due diligence as a consumer has become a nightmare.
