Haha! Same for me (this being tptacek's comment, not the article).

It's like reading an introductory explanation of what an electric vehicle is ("a car with an electric motor that one can recharge at home") and then a comment saying "no, no, no, internally the whole powertrain is completely different, there are inverters and relays, etc."

Yes, exactly. I don't object; it's salutary to find out you don't know anything about topic X. It's just disconcerting after having read and understood an article purporting to explain topic X.
