Yeah but the checkout button on the insecure cart page could be changed so that it instead points to http://www.apple-payment.com/.. http://www.apple-payment.co

Yeah but the checkout button on the insecure cart page could be changed so that it instead points to http://www.apple-payment.com/.. http://www.apple-payment.com/... or any random malicious "checkout" page which then steals your CC. They've compromised the security of credit card details users will at some point enter by doing this. It's insane if that isn't a priority.
