Digital Sovereignty isn't for Sale.

You do not need an Open Source Program Office.
Every digital sovereignty talk ends the same way: set up an OSPO, and the idea gets filed under someday. But the office is not the point. It is a container for the jobs your vendor used to do, priced into the license fee and now yours to own. Name who owns them and you are ahead of most.
