I'm only looking for facts, not trying to stimulate FUD etc: didn't RedHat announce something that seemed to decrease their commitment to Fedora, or was that just RHEL and CentOS type enterprise stuff? (I'm a Fedora user, and I do/would not look forward to switching.)
No, Fedora is upstream. Nothing changes for Fedora. Original CentOS is discontinued, CentOS Stream is downstream of Fedora but upstream of RHEL. RH has taken measures to thwart clones of RHEL.
