With this move Tesla effectively gave up on the $7.5 billion package from the us government to build new infrastructure. Since it was paid with private money, it doesn't require to be nationalized. It's also accessible to anyone, with prices that are reasonable

Also, I don't know how efficient is the government in the usa, but in my country the chargers built by the semi-nationalized electric company are almost always broken because they don't really care about profits, they have the unlimited government budget, so what's the issue if a charger breaks and gets fixed after 2 years, making zero revenue during that time?

Good news! NACS is being adopted as an SAE standard (J3400)
