This is not at all accurate. There have only ever been 3 DC Fast Charging connectors in use in North America. CCS1, Tesla's and Chademo. Chademo was only really used on a couple of cars and most popularly on the Nissan Leaf. Chademo is effectively dead in the US. Which leaves CCS1 and Tesla/NACS/J3400 (which is all the same thing.) All manufacturers are migrating to Tesla's plug. This will take time as it's not a trivial change. Any EV driver is well served to carry an adapter, but it's not totally necessary. My BMW EV does not have accesd to Tesla's supercharging network (so no need for an adapter) and I have driven over 50k miles in the last 18 months on road trips all over the US.
