In practice, I think that what we're actually seeing is what happens when customer support is seen as a cost center. The company could spend more on support, or they can add a notice to the call waiting and call it a day.
Good examples are John Legere (TMobile CEO). How often do you see the CEO of Verizon or ATT actually showing a human response to customers in public?
Obviously a CEO a who values support is important, as obviously support is important.
