If I was starting "another CentOS" I would ensure that companies above a certain amount of revenue had to pay (either in licensing fees or in engineer time). Non-corporate and FOSS uses should remain free. The reason I suggest this is differences in user engagement.

That's just RHEL; https://www.redhat.com/en/blog/extending-no-cost-red-hat-ent... for FOSS and https://developers.redhat.com/blog/2021/02/10/how-to-activat... for non-corporate users.
