In my headcanon, I still read k8s as "network of cubes", as in Borg cubes, as Kubernetes itself is a poor man's Borg (as in the thing that Google runs on, named after Star Trek Borg, known for cube-shaped ships referred to as "Borg cubes"). The whole kyber thing sounds like an explanation after the fact, to detach from the Collective legacy.

Have they ever released the full internal Borg toolset and software ?
