You have to experience trying to sell on Amazon to understand that their policies forbid quality markers like stating patents. The entire system is rigged so that people who design and make products can’t even differentiate from the knock offs.

Amazon needs the competition so there is someplace on the internet where domestic manufacturers can have a leg up.

Can you expand on this? Do they have rules that stop you from saying things like, "Patented Blozzle Technology prevents the widget from snagging on gadgets" or listing a patent number in the description?

Amazon, much like a judge and jury, will not find your "clever loophole" interesting, and will deny you. Even if you have done everything to the letter, they may still ban you should they have their reasons.

Having worked for a firm that attempted to publish applications to the Amazon app store that would have in some sense competed with their own (reading app), we had an experience where we did everything to the letter, our app would be "approved" but would magically be unavailable for download when we attempted to download it. Some form of hell-ban applied to the app store.

Our C-Suite had previously sold a firm to Amazon and had a rolodex of high-level contacts at Amazon who all went from "good friend" to "cold shoulder" when asked if they had any clue or guidance from their former colleagues.

They are a shifty, immoral firm.

there would be third party scrapers to compare prices. I don't think you can really solve the problem of poor quality dropshippers, except if the platform mandates a return policy which doesn't cost the user.
