It doesn’t have to be nationalized, but it doesn’t make any sense for a civilian to be able to unilaterally make decisions like that while under military contract. At the very least, any decision to change or influence the contracted service while the contract is active should require some sort of review and approval. Maybe there’s a good reason it’s the way it is, I’m just a layman, but every time I hear about this it just baffles me why it was even allowable for Elon to make the call he did, or any call for that matter.
