Free as in Freedom

I just ran across FAIFzilla, the "no-frills online version" of Free as in Freedom: Richard Stallman's Crusade for Free Software, an unauthorized biography. I started to read it, then started to think I'd rather read it in a more convenient book form, then followed the link to Amazon.com. But, well, it just felt wrong to buy a book about RMS from Amazon.com, even though FSF ended their boycott. I wonder if the author, Sam Williams, realizes the irony of that link.

Update: I forgot to mention that I found out about the book from an essay by Eric S. Raymond which has some criticism about the book.
