Although what I’m about to say would be taken to a logical extreme by some, that is just fallacy —

It is of course immaterial that someone later becomes a government employee. If we were to pass a law along these lines, then any expert who later becomes a government employee would not be entitled to the protection of prior intellectual property.

Barack Obama penned many items prior to the commencement of his government employment. His interest in those pieces where he discussed topics relevant to his interests or expertise in constitutional law is not abridged because he entered public service.

In this case with Prasad, there is other nuance, but none of it material to that specific point.

A much more fruitful focus would be on the doctrine of fair use and the examination of the credentials and claims of those who do enter public service.
