Yes, and like their other MS Research projects it's licenced under the 'Microsoft Research Licence' which means that whatever modifications/enhancements you do to the code can only be used within this academic setting. HOWEVER, Microsoft themselves can use your modifications for whatever purposes they want, like sell them. Sweet deal...

As with any other software license (including the GPL), if you don't like the terms, don't use it.

Isn't it a bit misleading to put the MRL and the GPL in the same league? I agree with the "If you don't like the license, don't use the software" attitude, but the terms of the MRL are quite restrictive.
