This response is completely unacceptable.  It takes no additional, and
actually less, effort to say:

    Thanks for your interest but you will have better luck dealing with
    Redhat directly.  This project repackages their software, so if you
    work with them, any issues you help fix will automatically be
    applied to CentOS.  2 birds with 1 stone, eh?  Pretty nice!

If you can't figure out how to say something in a constructive way,
don't say it.  Allow others who can, handle it.
