Cool trip through digital audio broadcast, but I'm left bit puzzled by the last bit about cable vs PON networks. How are coax networks fundamentally better than PON fiber networks? Sure, in a lot of places they have the very tangible benefit of actually existing and covering tons of (potential) customers. But they're often old, require upgrades and retrofits to be DOCSIS 4 compliant. And in places where coax networks don't already exist, I very much suspect that PON fiber is way cheaper to deploy and operate [citation needed].
