My totally subjective opinion: In US/Canadian telecom, any business formed from legacy near-monopoly ILEC (incumebent local exchange carrier) staff, they neither have a clue nor give a fuck. It's a corporate cultural attitude left over from days when ILECs truly were the last-mile monopoly carriers in many cities.
In this case Centurylink is composed of former Embarq, Qwest (USWest) and other ILEC entities.
My opinion also applies to entities like Bell, Telus, Verizon and Frontier.
If you look at the people who run the core routers of their ASes, sure they know what they're doing, but they're so insulated from actually talking to a customer through myriad layers of corporate bureaucracy, that their clue level might as well be irrelevant.
