I don't think Drew would disagree with your point, given he has been vocally critical of the GNU project due to the continued involvement of Stallman and those who support Stallman.

However, it's important to note that practically it's not clear that GNU actually need a CLA if they wanted to pull such a movie. Contributions to GNU projects are GPL-x-or-later licensed, and GNU are the authority to declare something as GPL 4, even if it contained language that allowed the project owner to close the project.
