LOL! The article is wrong on that. Fedora is Red Hat's test bed. It is very far out front on RHEL. In fact RHEL 7.5 (current version) is running kernel 3.10.x, while Fedora is currently running 4.16.15.

That mistake surprised me as well. They said the same "clone of" about CentOS, which is actually true in that case.
Fedora is a clone of RedHat like a Ferrari is a clone of a Dodge Dart. They're both cars, and they're more alike than either one is like, say, a bag of carrots...
