I can see one good reason: the rest of the auto industry is playing catch up with Tesla. Nobody else afaik is even able to do over the air updates (reliable updates, that is). They have a charging network, the competition basically doesn't and can't seem to get their act together, and that's not even really a technological issue.
Isn't the "charging network" a thing that shouldn't be vendor locked? Imagine if every petrol pump was tied to specific makes of cars? Any current vendor lock-in of charging is surely at risk at being legislated away, by insisting that EV charging is done through a standard port like refueling petrol/diesel vehicles. If governments were serious about electric vehicles as a way of improving air quality they would legi…
"Tesla is aware of these problems. CEO Elon Musk first floated the idea of sharing its Supercharger network in 2015, but with only a few hundred Superchargers operating at the time, the proposals did not gain any momentum."

But instead of doing that, other manufacturers designed much inferior alternatives that are a UI/Customer experience nightmare to use.
Tesla Supercharger:
1. You pull up.
2. get out of the car.
3. Plug-in the cable and charge.
It's that simple and intuitive. You get billed from your Tesla account. Because the transaction is tied to your VIN.
Other EV/High Speed charging:
1. You pull up.
2. Get out of the car.
3. Figure out how to use the menu.
4. Grab your wallet to either pay via card or RFID.
5. Pay and cross your finger it works.
5. Finally you can charge.
