I don't think that's true, exactly.  As far as I know, rebuild 
distributions never had the "Enterprise" features*.  Critically, I think 
that a lot of people mistakenly believed that CentOS *did* have 
Enterprise features, because it was rebuilt from RHEL code, and that 
misunderstanding underlies a great deal of the negative response toward 
CentOS Stream.

*: "Enterprise" features include but are not limited to:

 1. Minor releases with independent life cycles / Extended Update Support
 2. Classification for updates (security, bugfix, enhancement)
 3. Live patching for kernel security vulnerabilities
 4. Support
