I read it the other way around, with RMS being the one offended and trying to correct everyone: the people maintaining glibc agreed to change part of the documentation because it wasn't serving a useful purpose, either as technical material, core philosophical material, or as material reinforcing one of those two (which can include a carefully-crafted joke, don't get me wrong). RMS got offended and tried to force them to keep it.
