If Tesla wanted theirs to be standard, they should have made this move years ago. They missed the boat, and are now scrambling to avoid having to change their own sockets.
CCS was released slightly before the Model S (first to use Tesla's connector). Both were developed at the same time. At the time, there was no viable alternative for Tesla. Now, there is no reason to revert to a significantly subpar option.
It's very difficult to find charge stations that aren't Tesla, and when you do, they're often used for general parking.
Where I am (Oregon), public CCS charger locations outnumber Tesla chargers several times over. There are huge areas of the state that have CCS chargers, but no Tesla charging capacity.
My next EV will certainly not be a Tesla, for that reason.
A family friend returned her EV after realizing how dumb the situation is here. Perhaps it's a regional problem.
