> most Kubernetes deployment don't even run containerd anymore

I assume you mean moby, which was used via dockershim in Kubernetes until support was removed in v1.24.

I can't find a reliable source, but I believe containerd, followed by CRI-O and alternatives, are the common choices of container runtime for Kubernetes.

It was called plain docker originally, the Moby rebrand came much later and not everyone is even aware that it happened, because plain docker was already much less relevant when they did it (vs k8s, which was already becoming the default by then).
