I was looking at my G+ news, and since I'm following Debian I saw a link to this:
March 1st, 2013
The Debian Project is pleased to announce that, according to the terms of the new trademark policy, Debian logos and marks may now be used freely for both non-commercial and commercial purposes. The Debian Project encourages wide use of its marks in all ways that promote Debian and free software.
Pretty nifty, eh?
