I understand that, so I only leave reviews on the product if it's a single seller, selling their own product. I think "this product comes with a scam offer" is a valid review of the product.
I also leave seller reviews, of the seller, on the seller's page. (Many people don't realize you can do this.) These are deleted too.
I went down a long odyssey recently of trying to get a refund for a food item that was four months expired the day it was delivered. Amazon refused. I escalated it. Amazon refused again. I tried to leave a bad review. Amazon deleted it. I reviewed the seller itself. Deleted again. Kept trying over and over again for several days, making ever so slight tweaks to conform to the policy. I came to the conclusion it was simply impossible to leave a negative piece of feedback.
If you did stop buying from them, I hope more people follow your lead!
I hope for a future where their monopoly position is litigated away so that there is a fair marketplace with other options for next day delivery for common household items. I prefer to shop in brick and mortar stores, but there's definitely a legitimate use case for next-day delivery of household supplies. I have a family member currently experiencing severe mobility issues who lives several hours away from me in a rural area, and unfortunately Amazon is the only way I can get things like household medical supplies to her door on short notice.
