Kxra sez, "Defective by Design, the Free Software Foundation's campaign against DRM has just released a new graphic to mark DRM-free works on the web. The DRM-free label quickly communicates the DRM-free status of files, increases in value as more distributors adopt the label, and adds value to being DRM-free by linking to an informational page about DRM. The logo is already in use by O'Reilly, Momentum, the Pragmatic Bookshelf, and Magnatune. It is available in a few different styles with source files under CC-BY-SA 3.0."
New and improved label for DRM-free files (Thanks, Kxra!)
