You are absolutely right. I was excited because I can finally read the code and learn something from it.

But of course the implication "open source -> I can use it anywhere I want" is broken in this case. The author should have been a little more careful in not abusing that term, even if this was posted on his blog.

I am well aware of that licence, I myself had to use it for some code I wrote while at MSR [1]. I was not happy at all about the non-commercial clause, but it was either that or not releasing the code. I guess the same happened here.
