Red Hat 30th anniversary
What would you say are the main contributions of RedHat to the FOSS world, from its inception until this time (or 2019 if we want to split hairs)?As a devotee Debian (now Devuan), I've never been fond of RedHat/RHEL/CentOS as distributions and they always felt clunky to me somehow. But I am vaguely aware that RedHat has been involved in kernel development and the development of various apps etc. What would you say are the most prominent and "redeeming" of those?
