We have this impression of the reliability and stability of the POTS network partially because it is ubiquitous and invisible. Yet, as someone who has spent most of my adult life working in and around copper twisted pair, I can tell you POTS isn't as "reliable" as you think.
You have the impression that POTS is reliable because there's a small army of men and women maintaining it. AT&T is claiming that it is costing them a fortune to maintain the copper twisted pair infrastructure to the standards dictated by the FCC for a rapidly dwindling number of customers. People are leaving copper-pair services by the thousands every day: some are going wireless, some are going to pure-play VoIP providers, and even the "cable company" (or the telephone company's own fiber).
Copper wire only lasts 20-30 years hanging from the side of a pole, on average, before it will likely need to be replaced. Especially in urban areas, where cable replacement isn't cheap, most of the landline phone companies are staring down the barrel of 50-60 year old copper infrastructure that may have as many as 75% of the pairs condemned.
Let me put it this way. No IT department for a business in a 100-year-old building facing a phone rewire job would replace all that 50-year-old 25-pair with.. more Category 2. The minimum they'd pull is Cat5e or "6", and even more likely they'd pull a significant amount of fiber, if not to the desk at least to a departmental wiring closet. That's the same decision the phone companies want to make.
From a strictly technical/engineering perspective, it's 100% the right choice. Copper loop is functionally obsolete in almost every way.
