My take on this is no they don’t. As long as they are truthful they only report on the quality of the product and prevent many people of spending a lot of money from losing it by buying something that doesn’t work.
If your product is shit your company does not deserve to be shielded from the backlash, this is the core of (classic) capitalism after all.
The problem on Amazon, especially for all these dropshippers that all sell mostly the same products: if you don’t have the best rating, nobody will buy your shit. So here it might indeed kill the company. Or at least this listing.
Which…fine. Don’t build your business on a faulty model.
