Organizational inertia can be cut through without causing a tremendous amount of pain and disruption. Stopping things by default is a very lazy way to do it. Doing it this way is a strongman fantasy that inflicts large costs: now your employees aren't doing their jobs, they're going through a round of "justify yourself" (when you should have had the organizational controls in place already).
And there's nothing new about this strategy, either. I read about these tactics decades ago in management self-help books. They were just as crappy and inhuman then as now.
