Someone with that level of experience and recognition should be capable of either implementing the function themselves, or at the very least have the professional network to know a number of people capable of doing so for HPE.
I would also expect significantly more tact and professionalism.
The email record screams "BOFH bench warmer."
Edit: the more I think about this, the more I think he probably sold himself to HPE as being able to give them what they want from FORTRAN due to his committee membership. Which turned out to not be true, thus placing his salary at risk.
