Why??? Sorry, but that's not at all clear to me. Point 3c says: "(C) If you distribute any portion of the software, you must retain all copyright, patent, trademark, and attribution notices that are present in the software." Doesn't this basically mean that you can't just make a derived work that is the original work but with the copyright and other statements from the original work deleted? I'm not convinced that is GPL incompatible. I.e., I agree with Martin that this isn't clearly incompatible. There might be patent restrictions in the Microsoft license that could render it "GPL incompatible". But those restrictions seem to me, as stated in their license, might not be a problem. Here's the statement: "(B) If you bring a patent claim against any contributor over patents that you claim are infringed by the software, your patent license from such contributor to the software ends automatically." > Simplest solution: MS employees should ask lawyers at their company > whether MS-PL is GPL2-compatible or not. Said MS employees are naive about such stuff. Moreover, it doesn't matter what the MS lawyers say about GPL compatibility of their license, since it doesn't make it so. Anyway, the real question isn't "is the license GPL compatible", but "is code under this license suitable for inclusion in SAGE"? This is not a well defined question, since it depends on the community, which is why I greatly value your feedback.
