RMS is gonna be RMS. I just wish he was a more realistic advocate of open content. Creative Commons has taken off while GPL v3 is rarely used.
Creative Commons licenses aren't meant to be used for licensing code, and GPLv3 isn't meant to be used for non-code projects.
Case in point: If you click on "eBooks" from the submitted site, you'll download a one-pager PDF written by RMS, and released under a CC license.
