This is a new rephrasing of an older mantra, which is to use fewer words when possible. The writings of the greats in our field exude this quality, for instance those of Dennis Ritchie. Mind you, he does use the aformentioned words, but they are often necessary, for instance, using the wording "simple shell" is true, because the shells he developed were indeed simpler than the ones before, and provably so.

The only twist in this new take is that it has an issue with commanding language using such words, and I agree. If you are telling me how to do something, there is no need to qualify the effort, because you don't have that information and neither do I, so the language ends up being verbose and, more crucially, incorrect.
