The argument you've started here isn't meaningful. The project we're talking about doesn't (AFAICT) declare any license, so the fact that it's not open source (in the usual sense of "released under an open-source license") hardly warrants arguing.

The "problematic" bit is that the project's page describes it as open-source, says "you can even make improvements", etc., though the project isn't actually licensed that way (or at all).
