Yeah, 10 years down the line RHEL is pretty much guaranteed dead. Probably say goodbye to Fedora as well.
However, Red Hat is _far_ more than RHEL. They actually build a ton of OSS that's used in RHEL and elsewhere. Ubuntu does little more than repackage Debian. That's not a criticism. They package well, and they know how to polish. But there's no replacement for Red Hat as a company.
And if one really needs a "one click out of the box" desktop distro, then Mint.
Ubuntu made big inroads on the desktop in the early 2000’s, and now those people are running their own infrastructure.
Conversely, non-opinionated might not be good, but it's guaranteed to be not bad.
I've been doing this crap way too long to want to configure everything myself.
I wonder how this change will pan out across the entire Linux-sphere. I’m wondering and I’m trying not to be pessimistic.
