Why does Coinbase not support BIP 70 (Secure payment protocol)

I recently noticed coinbase does not use the BIP 70 standard for merchant payments. This is highly questionable since this enables man in the middle attacks. The Bitcoin address you need to send the funds to can easily replaced by a hacker with his own address.http://bit.ly/2fepD0L BIP 70 users can easily confirm if they send bitcoins to right receiver by verifying the domain that issued the payment request (just check if it is bitpay.com or coinbase.com)./u/coblee via /r/Bitcoin http://bit.ly/2dTCXlq
