Yeah, of course it does. Fully agree. I don't understand the point you're making.

I haven't offered my definition of value. I just said that you can clearly determine the value to yourself by reading the landing page, it has the relevant information required (besides actually reading all the content).

And what of values inherent in privacy concerns?

It just seems like you're applying a very narrow view of what can be considered "value" here.

The "privacy violation" is not the value of the book, that's the cost to you.

We're not discussing the values inherent in privacy concerns, we're discussing the value of the book, and whether or not you can guess at its value before you give the guy your email.

You're talking about something else.

No, you're talking about something else. Obviously OOP's concern is about the value of the book vis a vis what is demanded of the recipient in exchange for the book.
