Even if they allowed sublicensing the license would be GPL incompatable 
on the
grounds that it would add licensing requirements not specified in the GPL.

Most legit copyleft licenses are mutually incompatable.  See 
for examples.

I'm still reserving judgement.  Their latest spate of openish licenses are
much closer to meeting Stallman's definition of Free Software than I ever
expected from that company.

E.g. it looks like will really be able to implement 
file readers for the MS-published formats.  They will have to calve a 
and jump through some other hoops, but they'll able to make it work 
without needing
to do full white-room reverse-engineering.
