Well, the first thought is that they borrowed the thrust technology and software from spacex. This makes sense, because in starship, they used to have a lot of pneumatic powered actuators for things like thrust vectoring control, then they switched to electric motors, because they are instaneously responsive for one thing (and I think more reliable as they aren't fluid based). From what remember, they originally used electric motors from Tesla, so makes sense that Telsa would in turn borrow from Spacex.
