Amazon does profit off the listing is my assertion. Without Amazon, listing's ability to damage at scale is limited. Can't we argue that it is one of the partners in crime?
Amazon profits off of it, but so do the shipping companies and payment processors that helped sell the product and increase its sales. I don't think a platform that provides a service should be responsible for those that use the service, unless they explicitly claim responsiblity by saying they guarantee quality of their merchants or something. If amazon is responsible for the damage caused by their products, than so are places like Craigslist and eBay.
