I asked RMS from the FSF about advice about the legal situation.
He agreed with me and thinks that iGMT has to come under GPL
as a combined work. 
He also sympathizes with your goal, but notes that the 
restriction is incompatible with free software, as well as with the GPL.
He added that:

I see no reason for you to keep an uneffective restriction which is
even legally doubtful in the license for iGMT. You might make it
a strong suggestion so that your cause is heard.
