I can tell you that even inside the company, everyone I knew who had the beginning of a clue ran Fedora. Only those with zero tech knowledge and who didn't want to learn ran RHEL... and they get it for free, obvs.
Probably some RH folk will now pop up to tell me I am totally wrong and it's all changed. That is 100% normal. You can ignore them. I do. ;-)
> they only have annual subscription
You are not buying the software. You cannot buy the software. All you can buy is a support subscription. That is what RH sells, not software.
