Pardon the possibly ignorant question, but what do the telecom companies have to gain by destroying their own infrastructure? I feel like I'm missing something about the US telecom market here. Aren't these companies making a profit on this infrastructure? Are they selling more profitable services and they want users to switch over? Are the maintenance fees that high?
In the U.S. rural telecoms access has always existed because of government mandates supported in part by government subsidies and taxes. It would definitely be more profitable to drop support for large parts (land mass, not population) of the U.S. entirely.
Indeed, and the same is true of other places where wireline telephone service is universal or substantially universal.
Wireline telephone service is something that should be thought of as akin to electrification or public transportation. It is unlikely to have happened guided solely by private sector profit imperatives.
