You can't unshift a paradigm like DRM for big media
DRM was pervasive in the music industry. It no longer is. DRM was pervasive in the ebook industry. We are beginning to see signs from publishers (Tor books being the most recent example) of a willingness to sell ebooks without DRM. "DRM-free" has become a selling point for smaller companies in the games industry.
It is not easy, and it is not fast, but it is possible, and it is happening.
