If you publish your code under MIT/X11 you explicitly grant others the
right to do this. Indeed, if you incorporate MIT code into a GPL
project you *must* add the GPL headers to the derived work. There is
no obligation to get permission from anyone to do this: you already
granted permission when you published your work under MIT/X11. If Paul
had removed your copyright, that would be a violation of your license.
But this is not the case.

So as far as I can tell, Paul Jakma has acted properly, and you and
Matthieu Boutier have acted improperly in trying to redefine the terms
of your license and add new restrictions after it was granted.
