Is Red Hat still relevant? You bet.

Hi Folks,

"Many Linux users don't seem to realize just how much Red Hat
contributes back to the Linux community. They are major software
developers on a number of projects not the least of which is the Linux
kernel. The Fedora Project site has a page entitled Red Hat
contributions to Free and Open Source software which lists most of Red
Hat's contributions."
