It's not just a PDF—it's 34 PDFs! Each chapter, sidebar, and other section is separate. It makes for a kind of minimalist DRM. (I don't know for sure that the publisher meant it that way, though the way the copyright notice is written specifically to allow only reading "on the World Wide Web" suggests they could have an inkling.) There's no impediment to randomly browsing the full text online, but if you want to load it into an offline e-reader you have to deal with all the pieces somehow. Not that difficult, but it might be easier just to buy it. Sure, overcoming this is a minor hurdle given a bit of effort, but you can say the same about cracking typical DRM. (I expect a lawyer could point out differences from the point of view of DMCA's anti-circumvention clause.) Then again, the publisher may not have that much of a clue. There's no way to pay for a single-PDF version. And look at the links where the copyright notice punts you for information on Class Use [1] and other Permissions [2].
