This is nonsense. Comcast used to be AT&T Broadband in my region and they are the sole provider of broadband access in my entire region of the Midwest outside of major metros. They have something like 1/3 of all broadband customers, that’s an upstart? What they actually are is a combination of pieces of smaller companies, some of their assets being made up of the “baby-bells” that the behemoths have re-acquired over the years.
