DRM is ridiculous. I have/had some 20 books on the market, all of them also as ebooks (PDF) and not a single one of them is DRM'ed. I refuse to sell ebooks on Amazon, because their ebook format is not open. This year I will publish my first EPUB book. Also without DRM. However, most authors just don't know and/or don't care. Either because they do not know anything about DRM or because they only care about sales, and with some publishers DRM is not an opt-in. Unfortunately! So, yes, I understand the frustration expressed in the article! Look closely before you buy any ebooks!
