In what way is this helpful to newcomers at all? It uses a ton of heavy jargon and no example code.
Besides, I'm not suggesting (or "demanding") that all articles explicitly state their target audience. Just that this one does a poor job of indicating it.
So I think it's a poor argument when the parent comment (to which I was responding) assumes an exclusive target audience: "not introductory programmers... more experienced programmers".
You could argue that one was supposed to assume that from context. However, I didn't make that assumption whilst reading, so I especially wouldn't expect "introductory programmers" to pick up on that either.
