I do use a command-line program as the only way to interact with GitHub (using the GitHub API), but I do not use GH CLI; I have my own implementation (which is much smaller than theirs). (They can see that I use my own, because of the User-Agent header, and they can also see what APIs are accessed.) (Git can also be used, but only for the functions of Git rather than the functions of GitHub.)
