The acquisition and procurement departments in many government agencies are often “independent” in that they don’t directly report to the agency. They’re more like compliance people that make sure you’re completing with the procurement laws and regulations.
And unpaid software licenses are a violation.
Now maybe the client in this case may have had some kind if ownership clause, etc. but in general, procurement people tend to be pretty neutral in my experience.
Then again, over only dealt with small contracts (< $500k)
