I think one of the problems with it not being true open source is that they are selling a commercial version @ the microsoft store for 14,950. I suspect this is why they choose this license.

I'd be interested if they would provide different terms for the source for the people that bought the commercial version, or if you would just be stuck with the binaries.

Here is the link to buy the commercial version: http://www.microsoftstore.com/store/msstore/pd/Microsoft-Res...
