That&#x27;s a good question.<p>Apparently Debian got the ok from the Software Freedom Law Center[0], but they distribute it as source only, and the binary is built on the end user&#x27;s computer (and they consider it then unredistributable).  This is different than what Canonical is claiming to do which is to generate the binary themselves.<p>[0] - <a href="https:&#x2F;&#x2F;lists.debian.org&#x2F;debian-devel-announce&#x2F;2015&#x2F;04&#x2F;msg00006.html" rel="nofollow">https:&#x2F;&#x2F;lists.debian.org&#x2F;debian-devel-announce&#x2F;2015&#x2F;04&#x2F;msg00...</a>
