It is profoundly dishonest to characterize patents using a trivial phrase like "one-click" and then pretend like that also means that the patent is itself trivial.
I know why you do it- it fits your ideology.
But it doesn't fit reality.

Until then I'll have to assume we live in different realities.
You mean a client communicates with a server with information, then returns some information? How delightfully ingenious!
Your idea of what this patent covers is incorrect. It is not a patent on the feature of "press a button to make a purchase and skip the checkout process" or "have a cookie so we know who you are".
