Microsoft was talking about submarine data centers powered by tidal forces in the early 2000s.
There have been talks of data centers on Sealand-like nation states.
Geothermal ...
Exotic data center builds will always be hyped. Always be within the realm of feasibility when cost is no object, but probably outside of practicality or need.
Next it'll be fusion-powered data centers.

If there's one large orbital datacenter, then sure, ASAT is a threat to it. But if it's a dispersed swarm like the Starlink system?
Good luck making a dent in that. You'd run out of ASAT long before Musk runs out of Starlink.
Otherwise? Go wild. The space doesn't lack for space.
And with all the LEO megaconstellations? GEO isn't as vital as it once was.
It would take zero anti-satellite weapons to take down Starlink. Just point a good old fashioned gun at the SpaceX engineer who can issue maneuvering commands to the satellites.
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.
