As I see it, the author want his software to be "de facto" not open source while retaining the Open source label. And he tries to achieve that by appealing to the kindness of the people: "I'm the author, please do like I say...".

IMHO the author needs to put the license he really wants (restricting the use of his project) and deal with the consequences. If you put an open source license to your project people make certain assumptions... like they can use your project.

If you want your software to be used in one and only one project and in a certain way, then it is not open source.
