UNIX isn't dominant in the areas you mention now either (no, Android isn't UNIX). It has a niche among free software users and in networking devices but it is not common in other areas.

I.e. your "decades of useful outcomes" argument doesn't favor the point you are making because the opposite philosophy (a more verbose userland) has many times more "useful outcomes". Therefore, according to your own logic (which I don't subscribe to because I think popularity is a useless measure of sound design) you "should stop and ask yourself whether it's just a matter of taste on your side or, even more likely, of ignorance."
