It actually kind of is. GNU logos are consistently incredibly ugly and show utter disdain for, or lack of awareness of, graphical design [0].
It could be almost like a philosophical point: "GNU software is utilitarian. We don't waste time on fancy graphics". Or it could be that GNU developers tend to be... developers. No designers in sight, and no appreciation for visual aesthetics.
True, but since it's Free Software you can release a version of the same code by yourself with a better logo. Nobody prevents you from changing anything, that's what's beautiful with GNU tools.
