Unfortunately for you, any such license would explicitly contradict

There may be source-available licenses with that constraint; you  
could certainly create your own as a derivative of an open source  
license (that allows itself to be used like that; not sure the GPL  
does).  However, such a license would not be open source, and would  
probably be shunned by the majority of open source developers.
