Amazon is currently permissive which splits opposition, this won’t always be the case, they will tighten the screws eventually as they have done in the past in other areas. Amazon because it’s so broadly used undermines the utility of chargebacks, you can do it but it’ll be a real hassle to not be able to use Amazon for shopping. A lot of people will just eat the costs, is Amazon knows this they will force the situation more often because it’ll make them more money.
