I doubt that. They'll probably sell an adapter that other EVs can use, in addition to selling an adapter that will allow their vehicles to use CCS1 chargers.Tesla will already have to deal with CCS1 if they really follow through with promises to open the network to other EVs.

Tesla Model 3, S, X & Y Charging with EVgo Fast ChargingNote Tesla got no traction in terms of getting people to adopt their proprietary connector, so I doubt they can work the Apple market share magic. EV charging just doesn't work that way.
