This used to be my rationalisation, but my understanding is that Shotwell is the driving force behind the commercial and Falcon sides of the business and that there's a quite strong cultural divide between that and the Starship/Starlink side of the business which is driven by Musk. Apparently there's a lot of culture clash there.
Culture clash between starlink and falcon has to be the dumbest thing I’ve heard. Falcon only exists in its current form because of starlink and starlink only exists because of falcon. Starlink is by far falcon’s biggest customer and starlink enables falcon to iterate and try things nobody that cares about their payload would.
