Not to mention that "open for others to use" is not the same as "developed by an independent trade association to remove undue influence from one company over the process", which is how it should be.
Imagine Tesla can't figure out V2H, so they deliberately exclude it from the connector to hold back the rest of the industry that wants to move forward with it. Is that okay for you?
The deal is for access to Tesla's supercharger network.
The superchargers cost money to produce, install and maintain.
The land on which they are installed costs money to lease.
Tesla installed, in US, over 12 thousand chargers and the rumored cost of a supercharger is about $50k. That's $600 million, not counting the land and other costs.
Those chargers are Tesla's property.
It would be preposterous for government to meddle in a business deal where Tesla sells access to their property to others.
Ford and GM are free to build their own supercharger network but I'm guessing that they would rather pay Tesla than spend $600 million and 10 years to build something that is only as good as what Tesla has today.
Why should it be that way?
Tesla created the best charger and people want to use it. What's the problem?
They've already opened all their patents. Objectively they are the most free and open car company in history.
