Why?
To defend against the thesis that although taste may be a subjective thing and there is no universally-agreed scale by which to measure the acceptability or otherwise of a naming scheme, some collections of syllables can indeed be stupider than others.
"Sound stupid" is a very subjective term. You don't like the names, others like them. And by now everyone knows you dislike the names.
That doesn't even remotedly make your claim that they are stupid true.
If enough people think they sound stupid, then they are.
