I am a contributor who works on the Google Cloud Storage FUSE CSI Driver project. The project is partially inspired by your CSI implementation. Thank you so much for the contribution to the Kubernetes community. However, I would like to clarify a few things regarding your post.
The Cloud Storage FUSE CSI Driver project does not have “in large part copied code” from your implementation. The initial commit you referred to in the post was based on a fork of another open source project: https://github.com/kubernetes-sigs/gcp-filestore-csi-driver. If you compare the Google Cloud Storage FUSE CSI Driver repo with the Google Cloud Filestore CSI Driver repo, you will notice the obvious similarities, in terms of the code structure, the Dockerfile, the usage of Kustomize, and the way the CSI is implemented. Moreover, the design of the Google Cloud Storage FUSE CSI Driver included a proxy server, and then evolved to a sidecar container mode, which are all significantly different from your implementation.
As for the Dockerfile annotations you pointed out in the initial commit, I did follow the pattern in your repo because I thought it was the standard way to declare the copyright. However, it didn't take me too long to realize that the Dockerfile annotations are not required, so I removed them.
Thank you again for your contribution to the open source community. I have included your project link on the readme page. I take the copyright very seriously, so please feel free to directly create issues or PRs on the Cloud Storage FUSE CSI Driver GitHub project page if I missed any other copyright information.
