Microsoft to issue "Community Promise" for C# and CLI

This part still raises my hairs:

Quoting:Q: What if I don’t implement the entire specification? Will I still get the protections under the CP?

A: The CP applies only if the implementation conforms fully to required portions of the specification. Partial implementations are not covered.

I'm no lawyer so I refrain from commenting until a lawyer reviews that, but I wonder how that would work with GPLv3 section 11.

I don't see how it can conform to GPLV3, as the failure to cover partial implementations imposes a significant restriction on the rights of recipients to modify the code.

Yes, but GPLv3 section 11 also mentions several things that apply only to the patent holder or controller. A 3rd party use creating GPLv3 code does not control the patent in this case.

I assume that someone with FSF is looking at it as we're speaking and that comments and analysis will shortly follow. I'll wait for readable version of all that legalese before I make up my mind.

Why are we looking for GPL compatibility on a license that isnt even on the OSI's license list?

p.s. GPL compatibility does not an open source license make, or rather lack of said compatibility does not mean that a license isnt an open source license. In this case however, it's a completely moot point.

Because the MS-CP isn't a source code license so it will never show up on the OSI list. IMB's patent promise isn't on OSI either. Neither is the OIN promise.
