Stop saying that CentOS mimics RHEL... It IS RHEL. They take their packages and build them. They strip all the Red Hat logos and other copyrighted things, but it is RHEL.
Exactly, no one is mimicking the other, it is open source where RHEL and Centos took from. Both are using it within their rights of usage.
