This is a most excellent place for technology news and articles.
To be fair a three-phase connector doesn't make sense in the US with their bonkers electrical system where you get either 110V to neutral or -110V to +110V.
Separate DC charging standards make no sense at all, though. From what Technology Connections says Tesla at least switched the signalling to be compatible, so all you need is a physical adapter. Maybe they figured that they don't want to fight all the other manufacturers, or make additional money from non-Tesla drivers using their network, or something.
