Tesla has consistently said the Supercharger Network is open for any manufacturer to adapt. "
"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."
"Tesla’s chief technology officer JB Straubel has strongly suggested that plans are now underway. He said to Electrek: ‘For things like Supercharger, we are actively talking to other carmakers and we are trying to figure out a structure to work with them.’"

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.
