because of cheap-o Chinese junk that has flooded amazon, to the point that 99% of the products in EVERY category, from bicycles to chairs to rucksacks to hard drives to cables to every(...)thing, I found a perfect AI solution to my search woes. I stopped. And combined with the fact that amazon now blocks seeing more than just a few reviews unless you log in (to provide them juicy data on what registered users watch, how long for, etc, etc) - I just don't shop on amazon anymore. If there's a SPECIFIC product I'm after, I check its price on amazon, just to make sure I get it cheaper, and only buy on amazon when the price is competitive enough. I think I might have one purchase on amazon this year, or maybe it was end of last year, can't remember. It's just not fun wading knee-deep in rubbish dump.
