As someone working in scientific computing, I seem to recall rumors from the grapevine that the Department of Energy and/or reviewers essentially said, "CentOS is identical to Scientific Linux. Why are we paying for this?" and pushed hard to sunset it. It's really sad because Fermi Linux was one of the first (if not _the_ first) free RH rebuilds out there back in the day. Huge props to Connie Sieh and the maintainers that followed for pulling that off. Really wonderful folks. It does certainly feel convenient for RH that the end of SL coincided with radical changes to CentOS.
