Just waiting for Rocky to make a similar announcement.
They're staying the course. tl;dr
One option is through the usage of UBI container images which are based on RHEL and available from multiple online sources (including Docker Hub). Using the UBI image, it is easily possible to obtain Red Hat sources reliably and unencumbered. We have validated this through OCI (Open Container Initiative) containers and it works exactly as expected.
Another method that we will leverage is pay-per-use public cloud instances. With this, anyone can spin up RHEL images in the cloud and thus obtain the source code for all packages and errata. This is the easiest for us to scale as we can do all of this through CI pipelines, spinning up cloud images to obtain the sources via DNF, and post to our Git repositories automatically.
2020 was such a shit year in computing. So many things got killed off. CentOS, Windows 7, Flash, and Python 2.x, off the top of my head, and probably some other things as well.
I mean yeah, most of these things were getting long in the tooth, but they were widely used and it would've been nice if they were all supported longer.
