My personal, anecdotal experience is that people's eyes glaze over whenever DRM is mentioned, especially in the context of e-books. "Whaddayagonna do?" seems to be the standard response, followed by "I like my Kindle" or "I don't really read e-books."
Rare individuals will continue to seek out DeDRM'd content and ways to remove digital locks imposed by monopolies.
