My personal theory is that Helm may be ok for distributing a pre-packaged solution to other people. Then people mistook it for a tool that should be used in-house to deploy a company’s own systems, where it makes much less sense.
Using one of the most horrible templating languages since ASP. Helm is what happens when a devops team decides to yolo into software development.
What's the issue with kustomize? It works well for us.
