This is Hacker News, where it is generally understood that most people will have a fairly technical background (it's not called "Hacker News" for nothing). And the review is on Ars Technica, which also targets a technical audience. John Siracusa's reviews of new versions of Mac OS X are famous, as they provide all of the technical details that most other reviewers don't. I understand that's not what you are looking for, but that's what the target audience of Hacker News and Ars Technica wants, and I certainly appreciate it.
Is this your first time reading one of John's reviews ? The last few that I remember even had a programming section of some kind :-) And he does mention before beginning the Internals section that people can skip it and the geeks wouldn't mind.
