Why shouldn't engineers "mock" the things that they think are badly designed? But by "mock" I mean criticize. In fact, as an engineer, it's one's professional duty to criticize bad design, as good design is essential to the endeavor of engineering progress.
Good engineering design vs bad engineering design is what prevents bridges from collapsing or Mars landers from crashing.
But I hear you: sure it's quite possible to do arithmetic using Roman numerals, and if that's what you're used to, you probably don't want to hear that you've been doing it suboptimally. And all these people clamoring for a change to decimal are just an unbearable nuisance.
