Although it appears to be a binary-only download claiming to be free of telemetry and non-floss code, it does not share the fork itself, what am I missing here

Although it appears to be a binary-only download claiming to be free of telemetry and non-floss code, it does not share the fork itself, what am I missing here ? EDIT: "This is not a fork. This is a repository of scripts to automatically build Microsoft's vscode repository into freely-licensed binaries with a community-driven default configuration."
