This is a technical person blogging for a technical audience. If you are not tall enough to ride this ride and aren't interested in growing, maybe find another ride.

If this were a project blog post explaining their latest features, I'd agree with you. If the point is outreach, then yes, they should make it accessible. But he's telling a story. A story that requires a relatively deep understanding of the history and practice of operating internet services. Him writing "NTP (Network Time Protocol)" will not make the story much clearer. And if he explains the whole background, then it's no longer a story, it's a general-audience essay. That's a lot of work for you to expect from somebody that you aren't paying.
