I buy the books I want, DRM or no. I remove the DRM pretty much straight away (though, since almost all of my ebooks have been from MR's ebook vault, I've obviously not had to do that very often).
In regard to the "encouragement" of non-DRM, while I would normally feel no compunction against downloading a darknet ebook of a pbook I already own (but would only do so to re-read, or if I'd bought the pbook but wanted to read it on my Iliad), I
did buy Clive James's
Cultural Amnesia in ebook form, even though I had the pbook and had read it. I did so because I like it so much and I knew I'd get more out of it as an ebook (using it for easy-accessible reference, and inspiration for more purchases) than in it's pbook form, and because he/the publisher jumped in with it DRM-free. It wasn't a conscious decision to "encourage" non-DRM - more of a "Thank-you" note (plus, I'd been bitching about the lack of it in ebook form for a few months
).
Cheers,
