You probably want to work with the FSF on this. It's already in their queue.
The preliminary conclusion was that it is at the very least GPL-incompatible (choice of law clause in section 6), possibly non-free because of the PRC provisions of section 7 (Because "you should not be required to notify anyone in particular, or in any particular way" from the Free Software Definition) and that any object code is most certainly proprietary because of 3(a). There may be other issues.
Anyway, you probably want to work with the FSF on this instead of the Trisquel forums.
