This is a odd assessment. I agree certifications aren't all that, but having people learn them isn't about that. It's more that people don't feel like reinventing the wheel at every company, so they can focus on the real work, like shipping the application they've written. So companies like AWS, Docker etc, write things, abstract things away, so someone else doesn't have to redo the whole thing.
Yes I can host my packages and write tooling around it to make it easy. But JFrog already has all the tooling around it, and it integrates with current tooling. Why would I write the whole thing again?
I am responding to this part of the parent comment:
> I don't do a ton with Docker outside dev tooling, but I have never understood why private container registries even exist?
You know the options and have made a conscious choice:

So presumably you are not the kind of people I was talking about.
EDIT: I'm also assuming by the rent seeking part that the parent is referring to paid hosted services like ECR etc.
