If you’re not a globalist then wouldn’t you agree that Nebraska shouldn’t have jurisdiction to subpoena companies that aren’t incorporated in Nebraska? Your argument seems pro globalism
Firstly, Facebook clearly operates in Nebraska, and is thus subject to its jurisdiction.
Incorporation (in Delaware) is for corporate covernance, not for dodging local laws.
If a person is accused of a crime in Georgia, and the person had a safe deposit box in Maine, the Maine bank doesn't have to immediately give Georgia police their possessions.
But even if not, because Facebook has a physical presence in Nebraska, it is subject to Nebraska law.
