I have a couple of CentOS vms on digital ocean, just for some mundane stuff: bouncers/proxies. I mostly work with Redhat/centos at work. So, it is easy for me to manage my personal linux machines. It is about familiarity of tools: yum/dnf, locations of config/log files, etc. Yes, I could use Fedora. I understand that Oracle is Redhat's biggest threat. Rocky is a very small player in the scheme of things.
