Earlier quoted context omitted.
ApplePay seems to be doing things that others have basically done before, but doing it right in some important ways (credential on phone is for phone only, Apple doesn't get info on what you're buying), and I hope others follow suit.
Apple doesn't get info on what you're buying... and I hope others follow suit. As cynical marketing, I definitely see the value; in reality, not so much. Amazon, Visa, Petco, PayPal, BrianTree, etc. will still have a record of my purchases and we're on an inexorable march towards wider distribution of that data. How does Apple not having this data materially affect me?
What Apple are doing is removing the middleman, purely making this about transactions, not data. This means they're avoiding selling private information as a revenue stream.
This affects you, it causes a filter bubble http://en.wikipedia.org/wiki/Filter_bubble and means you're effectively less free to make a truly informed decision.
So not sharing your private information by default, is fundamental to your freedom. That's why we should all care, and why this is a great decision by Apple.
