I'd argue an even bigger issue is the way Amazon clogs up its search and product listings with sponsored results. Amazon isn't interested in selling you what you are looking for. They want you to buy some sponsored junk instead. This mindset permeates the site and IMO is the source of many current problems.
This is my biggest complaint. I look for CS and history books and get ads for romances. At least I figured that out. It turns out romance books make more money than any other category. Apparently, Amazon's ad inventory is mostly romance.
I remember a time when Amazon was a first class reference example for facetted search. These days I find it hard to set any meaningful filters on most of my searches. Even common ones like color and size are often absent. I guess there is no ROI in helping you find the specific thing you're searching for when you can instead spray and pray with "sponsored results" and keyword stuffing.
Sponsored results are marked as such and therefore are filtered out by most adblockers. This is not a perfect solution, as grifters also game reviews, but it helps.
