Same reason the F35 manufacture is awkwardly distributed throughout the US - the shore up political support (voting to kill jobs in your state is usually unpopular) and dip into as many subsidies as possible.
NASA got its support in much the same way during the space race. Spreading the jobs widely is a good way to get political support.
Data centers don't create local jobs once construction is complete. 40 people, most remote, can run a data center. The F-35 program claims to have over 250,000 people employed in its supply chain in the US and has large factories with high paying, often unionised jobs.
