Obviously don't know the story for why Amazon is pulling this product, but know that the supplier is the one that will be eating the cost - Amazon will 100% stiff them in cases where the product is deemed faulty.
Seeing as the 'product fault' here is bullshit, and the product seems to be an honest USA-made one, I'd say this is just more of Amazon being shitty Amazon and harming small to mid-sized US businesses.
