Starlink can even bounce data P2P, from one client terminal to another.
And how does decentralized ground infrastructure save you from a centralized executive?
Uncle Sam could bring Starlink down, probably. For anyone else, that would pretty much require WW3.
Executives don't matter as much as you think they do. No credible executive is going to cave to random death threats, and carrying them out would cause new executives.
Now, would SpaceX eventually become a shell of its former self without Musk calling the shots? Maybe. But if the shell you're worrying about is Starlink orbital shell, and the time you're worrying about is today and not in ten years? Killing Musk doesn't help you much.
