Generally, I approve of it. RHEL customers should be able to migrate to SEL fairly easily if they want but there would be some caveats in tooling changes based on kernel version.
Having a hard RHEL fork would make that transition easier for customers that want to leave Red Hat.
The open source drama isn’t going to be something most Red Hat contract signers care about, though. So SUSE will have make the transition more appealing in other ways.
