Wait...so your two options are buy from Amazon or pirate? Amazon is basically the worst corporation on the face of the earth. Supporting a small publisher -- especially a small publisher willing to publish Julian Assange, books about Bradley Manning, and books about Wikileaks, is basically a decent thing to do.
Actually I poked around the site more; it's not as bad as I thought (it takes normal credit cards, although authorize.net is kind of a pain). And the non-DRM ebooks are fairly acceptable. I'd still strongly prefer Amazon, but wouldn't pirate out of spite.

You can only buy this book direct from the publisher. Amazon isn't carrying it.
