There are over 80 Certified Kubernetes offerings

Now, how many of these are any good? I can't say I've tried more than a couple of these. Given past experiences with some of these behemoth companies, I'm skeptical that their offerings actually deliver a good K8s experience.

It would be nice if you could tell at a glance how many of these are forks, versus just installing unmodified upstream Kubernetes.

  0 of them are forks, if defined in the typical fashion of not followup upstream development. https://landscape.cncf.io/category=certified-kubernetes-distribution,certified-kubernetes-hosted,certified-kubernetes-installer&format=card-mode&grouping=category https://landscape.cncf.io/category=certified-kubernetes-dist... We've split Certified Kubernetes offerings into 53 distributions (meaning they make changes to upstream and/or add software), 35 hosted platforms (meaning they manage K8s for you), and 19 installers (meaning they just install vanilla K8s). Disclosure: I manage the Certified Kubernetes program and the Interactive Landscape shown above.

I actually wonder what the Kubernetes conformance suite is worth. For one I took a look at how OpenShift passes the conformance suite as it is much more locked down than stock Kubernetes (that's a good thing, I guess, but not exactly conformant). The answer is, they remove the restrictions before running the suite (https://github.com/openshift/origin/blob/master/test/extended/conformance-k8s.sh https://github.com/openshift/origin/blob/master/test/extende...). So in my view a default installation of OpenShift does not pass the Kubernetes conformance test. The fact that many software packages for Kubernetes do not run on OpenShift confirms this and challenges the worth of the Kubernetes conformance claim, probably for many other Kubernetes products as well. Afer all, what good is a conformance test when it doesn't ensure compatibility.
