RHEL hasn’t gone closed source, it still complies with the GPL. If they provide you a binary, they must and will continue to provide you with the source code. I feel like this is like when they announced Centos Stream as a “rolling distro”, their messaging is awful, and the optics are bad. I feel this is more to stick it to Oracle and unfortunately, Alma and Rocky are just getting caught in the crossfire.
Edit: spelling
I would never consider Fedora bleeding edge, but that being said, after the Red Hat lawyers forced the removal of H.264 I did end up hopping after 5 very great years with Fedora. If you’re up for learning something new NixOS is a lot of fun.
