Which is pointless to compare -
1. All the other cars are J1772 + CCS
2. So you'd have to provide adapters for every other non-tesla car, or replace every non-tesla port. Not just the 20k CCS ones, but the 96K J1772 ones.
3. They are claiming a false ubiquity to make it seem like now is a good time to do this. The point at which there are 3x other plugs than yours is not a point where others are going to switch to your thing.
In fact, they are almost certainly doing it because they see the train coming at them, and don't want to deal with it.
It's too late.
