Relation to rustdesk-org GitHub Org and suspicious Patches during Build Process

[lu1as]

Hi all,
I noticed that the Docker Hub image rustdesk/rustdesk-server referenced by the official documentation) is build using a fork of this repository in the rustdesk-org GitHub organization: github.com/rustdesk-org/rustdesk-server.
Further, I found that each git tag in that fork has a commit, that is not part of the main repository and patches the source code using a hidden secret during the build process (see build.yaml). This looks like an attack where malicious code is added to the final binary, although the commit is created and signed by the same bot user as many other ones, also in the main repository.

Could anyone explain the reason for that fork and why the file src/common.rs is replaced during build?

Thanks and regards,
