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.
replyI read that indeed they did use SpaceX technology.
