It’s not “unavailable” in any form, I followed the link and it can be had in paperback, hardcover and Kindle

That's interesting. I'm seeing the Kindle edition as unavailable on both the American and United Kingdom websites while overpriced hardback and paperback versions are still available for purchase. I checked twice.

It's probably some low-level leftist employee at Amazon taking advantage of the distinctively leftist environment at Amazon to make his or her little point. Someone else here has kindly provided a PDF link, which means it's widely available in electronic form anyway. The hell with the scummy little turds at Amazon.
