Kinda? We use Cloud Run because for our workloads GKE was a lot more expensive. So far, it's been great. I wouldn't say I've "left" Kubernetes, since from what I understand Cloud Run implements the Knative standard, which is itself built on Kubernetes. But much like it was predicted early on, I think Kubernetes is best used as a means of building an infrastructure platform, not an infrastructure platform in and of itself. You certainly can cobble all this stuff together and build a nice system, but it takes a lot of work, and there's probably a hosting company out there which already does something similar enough that you can adopt.

With this approach to hosting and deployment, I think Kubernetes' main advantage is that it opens the door to new kinds of infrastructure businesses, not that it makes hosting a website any easier.
