> they are betraying the gnu leadership
What do you mean?
My guess is that they're referring to the open letter from people working on many GNU projects calling for Stallman to resign.
I think this is the letter in question:

I still don't know what Stallman did.
Got caught up in an organized witch-hunt to remove him from power. Too much freedom of speech for the current FSF.
This is sad because it is such a nice and important project. But I cannot easily separate the work from the people who did it.
