Putting data centers in space doesn't really make sense unless you think it puts them beyond the reach of the law.
Fortunately; the space lawyers have already thought about this.
(For those unaware: Since spacecraft are all operated from the ground; if anything illegal is being done using a spacecraft, the government where the spacecraft was launched from has jurisdiction.
So if SpaceX should be doing cybercrime via Starlinks, then the FBI can get a warrant just like for anyone else in the country.)
