I think the article agrees with you, that Kubernetes is the defacto orchestration tool. And that Amazon, Google, Microsoft all offer k8s as a service. But the point of the article is that the part that Docker provides in that stack is not secure. There will be and already are alternative container engines underneath k8s. One day a simpler, quicker alternative will gain enough traction with Kubernetes (and others) and Docker will wither away. As a company. That happens all the time in tech. Websphere -> Tomcat -> Jetty, Apache httpd -> Nginx, VMs -> containers, etc. And it will also happen to Kubernetes one day. Yes, the helmsman will also be replaced by a nimbler modern replacement.
