This isn’t about internet. This is about landline telephone service and being able to call 911. For those that don’t remember, landline phones work even when the power is out. No big deal if you have a cell phone and service. Very big deal if you live in a mountainous region where you rely on WiFi at home due to bad phone signal and would have to get in a car to drive somewhere with service to get emergency help or, say, report a forest fire caused by power lines snapping.
In the landline era, AT&T agreed to be the provider of last resort and they didn’t do it out of the goodness of their hearts. They got something in return. And even if “superior” technology exists, it’s not superior for “last resort” situations. One day, maybe we’ll all have satellite internet as a fallback on our mobile devices and landlines really will be obsolete. But that day isn’t today.
