I suppose I can see how people are taking this piece that way, but I don't see it like that. It is snarky and ranty, which makes it hard to express or perceive nuance. They do explicitly acknowledge that "a single server can go a long way" though.
I think the real point, better expressed, is that if you find yourself building a system with like a third of the features of K8s but composed of hand-rolled scripts and random third-party tools kludged together, maybe you should have just bit the bullet and moved to K8s instead.
You probably shouldn't start your project on it unless you have a dedicated DevOps department maintaining your cluster for you, but don't be afraid to move to it if your needs start getting more complex.
