An interesting component of the switching off of POTS is that the quality of service requirements are different. POTS is regulated to require the phone company to maintain a certain legal quality of service with negative consequences for failing to do so.
Meanwhile, cell phone and VOIP services are "best effort."
The phone company put a pretty huge amount of effort into maintaining QoS (Lily Tomlin jokes aside) because there were consequences for not doing so. It makes sense that they would prefer to shed that responsibility.
