CentOS is essentially a doggedly faithful rebuild of RHEL. OEL adds
some tweaks, php-oracle, and various other mods they feel are
appropriate. Last I looked, it was available for free, but the updates
and support came with a price tag attached. This may have changed, and
I make no claims as to its stance.

There's also a moral implication. RH's staff has vocally supported
CentOS, and we contribute back to the RH community though bug
reporting, bug fixes, suggestions, patches, etc. We don't charge for
CentOS support, so we don't impact RH's business. Oracle on the other
hand DOES offer paid support, which impacts RH's business, and I don't
see any substantive attempts by oracle to give anything back to the
community at large.

Note, I have nothing against oracle nor do I work for RH, so this is
my own opinion, entirely speculative, and in rare cases incorrect.

During times of universal deceit, telling the truth becomes a revolutionary act.
