Bigger problem is the No Derivatives clause of the CC licence, as compiling or forking the code creates a derivative, so it's now a project nobody is allowed to use (or distribute) in any other form than their exact, precompiled releases.

In fact, as the GitHub terms of service specifically require you to allow forking - as recently demonstrated by the WinAmp project - I wonder if CC ND is even possible to be used in GitHub in the first place.
