I'm glad you mentioned the charging network. I have always said that is Tesla's big advantage for at least 2 years and maybe 4. I expect you are aware of Electrify America which is building a network with a significant number of charging locations? They already have some number of stations and are building many more. GM recently announced they will be partnering with Bechtel to build a significant charging network. Building the network doesn't really take so much time if you have the money which companies like Volkswagen and GM do. GM has invited others to partner and add to the plan.
I seem to recall someone saying GM gets their batteries from a Korean company, but I'm not sure. Or that might be the supplier of the motors in the Bolt. Perhaps you don't recall they have been making a hybrid for years, the Volt. It's not like GM is sitting on their hands. As I've said, conservative companies like GM don't jump in with both feet like a startup with nothing to lose. Also, GM is right in there with autonomous driving software. I forget the Asian company they are partnering with, but of all the other companies, GM is supposed to be the most advanced.
I have no idea what you are referring to about the ICE distributors. If you mean the dealers, why wouldn't they sell the electric cars?
No one promised anything. Now GM is saying they will have a full lineup of models by 2023. Volkswagen is bringing out EVs, many other companies have announced products due out in a very few years. No fake. They just didn't jump in with both feet like a startup with nothing to lose. It is not unlike WWII where America was the giant having been awaken.
