Yep. This is like writing an article about the increasing prevalence of gas generators and storage batteries, and saying that "electricity generation is turning into a consumer product". Really the centralized providers are failing with no hope in sight, so people are opting for distributed means to take care of their needs. If you tell someone they can pay a well-defined price for a device that might help them, or they can spend hours on the phone to make an appointment three months out that will result in indeterminate bills and likely further cycles through the bureaucracy, obviously they'll prefer the straightforward option!
