It's just at "end of profitable life".
For me as a phone nerd who would prefer to have a landline, but no longer have a good justification for it, and frankly I'm unsure if I even have a good drop anymore to my house (its not had service since 2010 - before I owned it).
I keep thinking I should reach out to AT&T and try to order services, but I just never quite get around to it.
Both PIC and Lead Cable pinhole overtime, the life of areal (either PIC or Leaded) cable is 30-50 years, the life of buried cable is 50-90 - all of this cable exceeds that point, and must be replaced.
The phone switches that are connected to the cable are all near or over 40 years old, and closer to 45-50 years old in design, the spares pool is surprisingly healthy (because so many switches have been decommed) but the software that runs of these switches is also near end of life - and in the sustaining engineering phase of its lifecycle.
There may be a life for some copper cable, but it will be literally the last mile. Which is a lot smaller in scope than what we have now.
I get angry when I see it, thinking about the history of free easements, tax abatement, subsidy, and other favorable treatment that the telcos received, historically, and how they can leave this perfectly serviceable infrastructure to rot.
Frontier bought assets from Verizon knowing full well they were going to ride this infrastructure until it was worthless while investing as little as possible. It is no surprise the copper plant has rotted on the poles, they treated their copper and fiber plants like trash in nearly every part of their territory.
There's no way it's getting removed in the next 50 years without a subsidy so maybe this is...OK?
Looking at what this is doing to the stock price of AT&T adds another potential item to your list:
Hedge funds pushing well-timed narratives to their benefit.

The post-breakup structure diagram is all I needed to see.
50/50 $T/$VZ long. Ez mode.
Maybe so they have an excuse to tear the wires down and end services in areas they don't care to service anymore.
Maybe so they can get more subsidies to run fiber that they'll promise to connect people with, but won't ever need to account for.
