It is not amazing this low IQ idiot continues to miss the points that were made upthread.
Yes Amazon won't share its transactions, but above you were writing about customers of Amazon sending transactions to other merchants, not Amazon. That you can't understand that the customer can be both a customer of Amazon (the cartel) and of non-cartel merchants and that doesn't violate any of my upthread points, shows how much you don't understand this thread.
I guess it still hasn't clued into your slow brain that the customer will have his transactions delayed by cartel miners when he sends his transaction on the open Bitcoin network to a non-cartel merchant. Yet when that same customer sends his transaction through Amazon's client it will be accepted with 0-confirmation and then added the Bitcoin block chain by cartel miners. (the cartel knows which transactions are theirs, the non-cartel merchants don't know which transactions are for a non-cartel merchant or a cartel and can't determine that from IP address, so the attack is asymmetrically in favor of the cartel)
I had explained all of this upthread. And I am not going to explain it again.
If you continue this intentional FUD, I am going to reply to every post you make with the first sentence of this post.
