License wise, it seems to be under GPLv2: https://github.com/linuxmint/Cinnamon/blob/master/COPYING
The issues before with Cinnamon is that it potentially required non-free
drivers for desktop acceleration like the standard, non 2d version of Unity.
I don't use it currently, but I read that version 1.6 and above has a 2d
session which helps Trisquel.
