Eh, as far as I'm concerned supercharger has by now become a generic term. Tesla can try to defend the trademark, but everyone (especially former Tesla owners) is still going to refer to all DCFC chargers as superchargers. Just like everyone knows "I'll have a coke" refers to whatever cola-type soft drink they have available.
To be clear - Tesla Superchargers all have Tesla plugs. Many are "J3400 compatible," but not all. "NACS" has no real meaning, other than the physical shape of the plug.
I can't tell you how many times I have seen this. Couple stranded wondering why the Chevy Equinox won't work on the old Tesla Supercharger. Trust the car, not third party apps on which to pick from.
I had to sadly point a Bolt owner to an L2 station a couple years ago - they first tried a V2 Supercharger, then they tried a RAN before it was open to non-Rivian vehicles (both in the same parking lot.) They had so little range left, they couldn't make it to the nearest open-to-all CCS station. (There was technically a municipal CCS station within their range - but Plugshare said it was broken, and if they had gone there and it was still broken, they wouldn't have even been able to reach the L2.)
