I agree with what you've said, but I think pretty clearly they're not talking about Superchargers. As any non-Tesla EV owner knows, the other DC fast charging options are pretty egregiously bad - Electrify America was most notorious I think for having abysmal reliability. In the past couple years, though, every other EV company has pretty much agreed to switch to Tesla's "North American Charging Standard", and an obvious major reason for this is that the Supercharger network is leaps and bounds better than the alternatives. This switchover is still in progress, so over the next few years you'll see CCS decline and more Superchargers.
