That's well on its way. Try to log into your bank (or countless other sites) using a VPN. They flat out turn you away. If you don't use VPN but use a different computer or connection you get grilled with "prove you're a human". I get that they are doing anti spam and fraud steps, but the logical conclusion of where this ends up is "if we don't recognize you from our mountains of tracking info we've been compiling, we don't want to do business with you".
