I would happily donate to Rocky if I thought it would really sustain it. But, honestly, they are too dependent on RH and finding ways to subvert their restrictions (and considering RH is pretty boldly clear that they dont want to give away the sources) makes it a whack-a-mole game that is not sustainable in my opinion. Been burnt with CentOS 8 once, and I'm not willing to go through it again. Atleast I know Debian wont go this way.
With enough support Rocky may grow by itself, without RH code. Like what is happening with OpenSearch and Elastic, and OPNsense and pfSense. And my gut feeling is that will happen.
