No one except those who explicitly went looking for this knew it. It wasn't made clear in any way.

Speaking of orthogonal. I remember this well. It was a case where Amazon stole back books people had purchased. The core concern at the time wasn't that Amazon had revoked a license to read a book, but that they had deleted purchased books from users' collections.

But at the end of the day, for many years Amazon had an action button saying "Buy now with 1-Click" with no legal fiction disclaimer. The button was identical to what you'd see when buying a bag of cat food, DVD, or anything else you'd flat-out purchase from them.
