I don't think they have ever said they are the sole owners of these production facilities. They have stated they are in partnership with several production facilities, so why is it such a farce to show the locations they are affiliated with.
The whole design of the company has always been car production, battery swapping, and technology.
Think of all the other companies that do this. A large scale bakery could be baking products for hundreds of brands, yet all in one facility. One of those brands may use several bakeries across the country to complete their product line. Does that mean they own each bakery? No. Would it be completely out of left field to show each bakery they produce their products in? No.
You can't take everything at face value. Did you notice they have a helicopter on the website too? Does that mean we are now manufacturing helicopters? No.
