Kind of weird to blame Kubernetes. As long as the application team operates their application and the platform team operates their platform, I would argue that you do DevOps. It's just that one team consumes services from another team. Kubernetes just happens to be a damn good "API" between the platform and the application team. Indeed, the application team is likely to build using code, whereas the platform team is likely to use scripts and configuration. But each runs the stuff they build.
