Confusing 

I tagged this article as confusing due to the Structure part. It reads, "Red Hat Enterprise Linux is largely composed of software packages distributed under free software and/or open source licenses, but is made available in a usable, binary form (such as on CD-ROM or DVD-ROM media or download) only to paying subscribers." However it does not explain what is the meaning of paying subscribers, i.e., what do the subscribers pay for? For getting RHEL in a CD-ROM. Definitely they don't pay 100+ dollars for getting it in a CD or DVD; they pay it for the support. However, the article skips that Red Hat offers support as abruptly says, "CentOS is freely available for download and use by the public, but is not maintained or supported by Red Hat." instead of using something like this: "RHEL, though licensed at GPL must be bought from Red Hat since they provide full maintenance and support for it. However, CentOS is not supported by Red Hat and is thus freely available for download and use by the public." I will try to cleanup the article once I get the time for it.   Talk
