It really, really didn't help a few years ago when AT&T went around buying up cable services so that they could implement a high-speed delivery system (which as AT&T, they were barred from doing themselves), and immediately upon completing sinking a couple decades worth of profits into the project, the FCC announced a regulation change which required them to give free access to the bandwidth to all communications companies....making billions of dollars just go "poof".
That’s it in a nutshell. AT&T doesn’t want to spend billions running fiber to every house just so some FCC 2-1 vote years down the line can cause them to have lost everything from a long term investment.
Look at FiOS. There are people clamoring for Verizon to maintain the copper that they’re trying to abandon. It totally undercuts the reason for the upgrade.
