Well, price dumping, I would say.

Normally centos users would "grow into" payed support from RH. Now Oracle claims to give them that support without cost.

Unbreakable Linux was never an attempt to have their own distribution, it was to undercut RH, and now they're found a new way to do that through Centos. It may cost Oracle money, but it costs RH more money, because, after all, they actually build a distribution.

Ideally, kill/buy RH, phase out Unbreakable, and cram in proprietary Solaris. But for now just destabilizing the RH ecosystem has to do.
