It was originally developed in 2003 as a continuation of the Red Hat Linux project… It is now the upstream source for CentOS Stream and Red Hat Enterprise Linux.
Did you notice how it says “Red Hat Linux Project” and then goes on to say “Red Hat Enterprise Linux”?
This is because RHL != RHEL.
From the Hyperlink on the Wikipedia page for RHL:
Red Hat Linux was a widely used commercial open-source Linux distribution created by Red Hat until its discontinuation in 2004.
OP is correct. You are mistaken for thinking RHL was RHEL. It is not.

You are right, my mistake for mixing the two.
Yup, in fact the base of RHEL 10 and CentOS Stream 10 is Fedora 41. For RHEL 9 it was Fedora 34 if I remember correctly.
