From Google's Gemini:
No, Amazon does not treat all third-party sellers fairly; many sellers report experiencing unfair competition from Amazon itself, including allegations of product cloning, manipulation of search results, and opaque, automated account suspension processes. While Amazon states it offers choice and opportunity, and some sellers thrive, these practices and systemic issues can be financially damaging, making the platform a complex and sometimes hostile environment for third-party businesses.
Before selling on Amazon all new sellers should go to Google and type in "does Amazon treat 3P sellers fairly" and read the entire summary. From there you might also want to Google: "Is Amazon an ethical company?" and "Is Amazon a corrupt company?"
This is not your father's river; the water is choppy and there is no lifeguard on duty, enter these waters with care.
