Amazons top priority is the customer, and thats how they got to this point, but everyone else suffers, from their 3rd party sellers to their suppliers to their own employees.
Here is a list of stuff Amazon does:
-Anti competitive behaviour on the buy box (Amazon doesnt have the product in stock. You have it, but your offer is still not shown)
-Banning sellers for no good reason, and you cant contact anyone helpful
-Screwing over their suppliers with Vendor Central, where they buy from you wholesale. They dont pay, they just say the goods were never delivered and dont accept your proof of delivery. I know sellers who are owed over 30k from amazon.
-Customers are able to send back items 1 year later. If you dont agree, they can file an “AZ claim”. If you get too manu claims, they ban you.
-Support for sellers is the worst combination of overseas call centers using some cookie cutter templates to answer questions. Often you are just copy pasting your question 5 times, until you get somebody with have a brain
-Use data from their sellers to create their own products and then force them out of the market
-creating huge incentives for chinese sellers which flood and undercut the local sellers
Its just a huge behemoth were nobody knows whats going on.
In my opinion this company needs to be split up by gov and reigned in.
But who knows, maybe more sellers will follow suit and the pressure will be increasing to change things.
