Yes, the author's assertion here is nonsense. A case of someone with a very small window of experience being certain that what he's seen couldn't possibly be an outlier - must instead be normal for everyone.

The article also has a constant theme of putting people down because of something he doesn't understand. The Helldivers 2 developers are "idiots" because he doesn't understand the reasons for asset duplication in games. Simple daisy-chaining of slave sockets off the master is "incomprehensible", "pointless", "arbitrary" and "a mess"; the person who did the wiring is an "idiot". It all comes across as unfortunately quite arrogant.
