Export: Yes, and your bank card is the property of your bank, even though its sole purpose is to access your own personal money. It kind of detracts from a democracy when you go through life with companies inevitably owning everything you thought you own - then again, it's always modern things. You wouldn't buy a bag of bananas and then be told that Banana Trading Inc. actually own your bananas still and you have to register them before you can eat them and that if you give a banana to your friend, you're breaching copyright. Thank god Activision don't make bananas (though Bobby Kotick
is bananas).
You signed a contract, basically this allows a merchant to confiscate your card if Visa/your bank tells them to. At least they're claiming a right they have. PayPal can claim copyright all that want on a receipt, it won't make it true.
Regardless your point has merit.
