While some people might post such comments for the sake of "intelligence signaling", the GP seemed to not know what "CTF" meant. I think he offered a fair and simple criticism, and I found your comment needlessly harsh and presumptuous.
Even if some people post comments like that as a trope, some - if not many - post them sincerely. I think the original criticism makes perfect sense: an article for beginners might better benefit its readers if it offers just a simple sentence or even link that briefly explains what the topic is before delving into its details. I personally have read a number of articles where I've encountered this problem, despite my familiarity with the given topic.
Also, I think it benefits the HN community at large if we try our best to read people's comments in a positive light, within reasonable, and encourage giving and receiving constructive criticism from one another.
