The thread head (<https://news.ycombinator.com/item?id=48612438>) makes the accusation of omission, but specifically as regards cost.

In my own initial response, I explicitly note "It does, correctly IMO, focus on..." and continue to list several of the issues raised, in addition to expanding both on those and adding others. Subsequent discussion seems to evolve from there, no longer anchored to the root.

Overall, the article isn't great insofar as it omits or demphasises some factors; but no, it's not obtusely bad or incomplete either. And your own characterisation of the discussion as a whole is itself inaccurate.
