And unlike a market, which is generally not owned by a single entity, this market is owned by the richest person in the world, so it certainly has the resources to enforce its policies.
It’s more akin to finding it on the shelf at walmart than a stall in a market, or more akin to making your payment for the illegal BnB directly to the landlord’s office.
“ Alongside its third-party marketplace, Amazon sells products to consumers directly, and The Markup found it was also selling banned items itself, revealing cracks in the largely automated purchasing system that feeds its massive product catalog.”
No one is suggesting this. It’s more like if you find one stall selling weed and then five hundred other stalls selling various illegal things, and then you go to the market manager and tell them and they lazily remove one or two vendors but don’t or any actual resources to work to root out the problem.
Found one stall in a giant market selling weed? Ban all sellers. Had one illegal BnB in an apartment building? Expunge all renters in the whole apartment block.
