1. Business culture thinks scale doesn't matter. Commentators writers talking about tech seem to get that it does (Stratechery, etc).
2. That faith in managers means the manager can just blame employees, in contrast to the idea that failures should typically be examined in terms of the whole system (Deming). This one was not surprising per se, since managers scapegoating employees is a super common phenomenon. But I would not have thought it was part of managerialism per se.
