Screencasts & Creative Commons

[Daniel Goldsmith]

Sorry to come lately to this issue, but:

Why are the screencasts being licenced Creative Commons BY-SA? The
Creative Commons licence includes many restrictive features, such as
the ones against DRM, which would make it unpalatable to both sides in
the free-as-in-speech argument.

I guess I'm just curious as to why this path was chosen rather than,
say, GPL or some other OSI approved licence. What specific benefits
are there to using this over the alternatives?

CC isn't 'Free' in the FSF-Free/Libre Sense, and it isn't Open in the
OSI/OpenSource sense. This places it outside the Ubuntu Philosophy[1],
unless I've missed something entirely. Note that I don't want to spark
a debian-legal type mess, I'm just curious.

Regards,

Daniel.
