@nicemicro You seem to be referring to how Red Hat conducted business before they shut down CentOS 8/9.
With their current setup, you as a paying customer get the binary packages, but you don't get the Complete and Corresponding Source Code for your packages.
All you get from them is "[it all comes from the git repos for CentOS Stream, some commits in there, you'll figure it out]". In theory you can find the information, but it's obscured for no reason other than obscuring.
If you redistribute what you got from them, as the GPL requires them to give you the right to do, they will terminate your support contract and access.
