AT&T are trying to decommission all POTS accounts and have picked up some resistance from the powers that (think they) be in California. No surprises there. What is interesting is the quoted source of data for the number of accounts for Landline service which is all too often the term used, incorrectly, to refer to POTS, and "landline" can include VOIP over cable that uses the existing in-home legacy copper pair wiring. That ain't POTS.
Back to the data source.
In a Newsweek article on the topic they get their information from what most normal people would consider an unlikely source.
According to the latest from the Centers for Disease Control and Prevention's (CDC) National Health Interview Survey, in 2024 almost 20 percent of American households nationwide used landline services alongside wireless phones, while 0.9 percent relied on landline services only—which amounts to about 3 million people.
Clearly, "landline" is more than good ole POTS, as it is entirely unbelievable that one in five households have real, honest-to-god POTS.
This is where the CDC is way out of line, out of their lane. How in the hell would POTS matter to disease prevention and control? Do pacemakers still use analog modems with acoustic couplers? Not very likely. Surely the CDC is not concerned that legacy FAX technology will be left stranded, which, by the way, will also not work with VOIP over cable (or anything else). And the only real reason to use a FAX is to contact a Senator or Representative (you figure it out).
The Bundibugyo strain of Ebola has claimed several hundred lives. So far. There is no vaccine, nor are there any effective therapeutic measures. Maybe if the CDC stayed in their lane they would have been working, effectively, to control and prevent this deadly disease.
