A lot wrong here, I'm sorry to say, and I'm really not a fan of Musk. He is absolutely not selling Starlink to be used by Russia. That would be shut down real quick. (They may be using black-market terminals, but that's a different question.)
And this new constellation will, as I understand it, be owned and operated by the US govt. Think like every single spy satellite ever: govt finds a contractor and asks them to do a thing.
