If that were true then none of this would be news. The CentOS Stream code is available to the public on git, but not the RHEL code. If the RHEL code was available to the public the outrage would have no reason to exist.
Even if paying customers have access to the RHEL code via git, they are forbidden from redistributing it (which is allowed by the FOSS licenses that code is under) or else the customers lose their license. This does not qualify as the code being available in my opinion, and in the opinion of the vast majority of the FOSS community.
Saying everything is fine and dandy in the RHEL world is FUD.
