It's a shame because it is just as effective as pissing in the wind.
Of course, by your reasoning this also means you yourself have designed a language.
I'll leave out repeating your colorful language if you haven't done any of these things.
Actually I think that's a reasonable argument. I've not designed a language myself (other than toy experiments) so I'm hesitant to denigrate other people's design choices because even with my limited experience I'm aware that there are always compromises.
Similarly, I'm not impressed by literary critics whose own writing is unimpressive.
