I've said, and I believe, that such free ebooks increase sales of the print version.
I don't know about you, but I really hate to have to read hunched over a computer screen. I can't even concentrate on on-screen material because of the ingrained habit of quickly scanning online text, rather than carefully digesting it the way I do with printed texts I can hold in my hand while sitting in a comfortable position. Just trying to concentrate on an extended on-screen text makes me restless and inattentive in a fairly short time. I generally look at a free ebook online just long enough to get an idea of the contents and whether they're something I want to read, and then look for a cheap used print copy to read it in depth. Other than that, the main benefit of an online text is the comparative ease of cutting and pasting blockquotes I originally found in the written text, compared to propping the book open and typing an entire passage.
I'm sure a lot of other people are the same way; the easier it is to sample the text, the more people will be interested in buying the book. So download the pdf's if you're interested; if you find the subject matter engrossing but get tired of staring at a keyboard, you can order a print version to read in comfort.
