Amazon has a "good" part: high quality goods of known provenance delivered quickly. Consumers love this part. And they have a bad part: random sellers with zero vetting selling garbage from an infinite number of procedurally-generated storefronts (love buying from Cayzzzqq, that's the store for me!). Consumers hate this part. (I ignore the human costs of Amazon's warehouses and look only at consumer perception.) Walmart sees this and decides: let's double down on the bad part!
