Zed does acknowledge as much but this is worth pointing out. For some reason contextual intent and "intended audience" are missed by programmers (who are typically stereotyped for giving answers that are a technical depth irrelevant to the recipients).

With that in mind, I think that describing the intended audience and context (as you and others in the comments have done) is a more valuable exercise. It makes K&R (or other book) accessible and applicable to a new generation. Such posts won't normally get much intention - they lack a certain rebellious and inflammatory flair we know and love so well...
