Tesla released their patents on charging back in 2014 in the hopes that others would adopt their tech: https://www.tesla.com/blog/all-our-patent-are-belong-you

Have you seen Tesla's charging connector? It's way superior to the bulky standardized connectors. And as said by others, there really is no other game in town right now for long distance travel in an EV.

Disclosure: I own a Tesla Model S.

I don't think it's entirely fair to expect Tesla to _wait_ for the rest of the car industry to agree on a standard that suits everyone. When the Model S was developed, no other car company except Nissan had any notable interest in electric cars, and no other company had plans to make cars even _close_ to Tesla's in terms of battery capacity.

Assuming that a charger network was necessary for success, which I would argue it was, waiting for the others to catch up could have killed the company.

Note that there have still been no large-scale deployments of charging standards with more than 50-60kW of power, which is half what Tesla is currently deploying to most of its charging stations in North America.

They don't even have to wait for an open standard, they could make their proprietary system one.

Tesla offered their implementation to all car manufacturers, including access to the Supercharger network, but none took the offer.

Not a Tesla fanboy at all but it's too early right now to settle on standards, it would stifle innovation.
