The way Amazon works now (or at least my understanding from past articles and seller interactions outside of the platform), for some of the items you are not guaranteed that you received the item that your specific seller sent to the fulfillment center. If an item has multiple vendors, you will receive probably the closest one, not the one from the seller you selected. If that item is fake (even though the seller you selected is selling original items), reviewing the seller would mean penalizing the good actor.

I had an interaction ~10 years ago with an Amazon seller that kept also their online store. They did not deliver directly to my country but directed me to their Amazon store that did deliver. I ended up getting a slightly different version (same item but a different revision). Talking to the seller, it was not one that they sent to Amazon; it also came from a warehouse in a different country.

I was under the impression that internally Amazon can track whose item you got because every item gets a tracking sticker when it enters the warehouse (or even sooner, if the seller labels them to save money). It would be a bit of an UI problem, but Amazon could take your review and just attribute it to whichever seller provided the item you received, instead of whichever you bought from.

Of course that's of limited help because you can't reliably order from a specific seller, but it would help Amazon fix the problem, e.g. by giving them an easy justification to reject to do Fullfillment by Amazon for sellers with low ratings.
