If this is true, then I don't see why CentOS is in the wrong and/or hurting RHEL. Cent is not selling support for their distribution. Although, I've been to their website and read a bit. It IS kinda quirky how they refer to RedHat as "a prominent North American Enterprise Linux vendor." Almost like they feel like they are stealing.

Just to address this one point, the one about the "North American Enterprise Linux Vendor," they were required to do that by Red Hat in a cease and desist letter. They used to just say they're a rebranded RHEL. Red Hat shut that down.
