I feel like this would have the result of Gell-Mann Amnesia, which is essentially what "influencers" rely on prior to sponsorship. Thing 1 was recommended, and others found the same benefits to Thing 1, so when Thing 2 is recommended it is assumed that the influencer's opinion is valid. Breaks down as soon as there is a disconnect, if people are willing to accept that their chosen influencer can be wrong, but in practice most people just go along with it.
