My sense is that this has happened over the last 20-30 years as overall competence has just dropped in many of these key positions. COVID was a good example of this - lots of humming and hawing about why decisions were being made, and garbled messaging about the reasons. Basically they get angry and defensive about blaming the "peanut gallery" or "armchair experts" while not being specific, because they themselves don't know why or how something is being done, and therefore being unable to defend their own positions from solid ground.
