Sure, I’ll grant you that at huge companies it’s probably easy to lose track of who is responsible for what and when resources ought to be cleaned up. But for small/medium-sized companies, using Terraform is sufficient. And while you can also use Terraform to manage resources on k8s, there’s a lot more friction to doing so than using YAML + `kubectl apply`. It’s far too easy to `kubectl apply` and create a bunch of garbage that you forget to clean up.
