That's fair. Having to set up a Ruby installation to run a utility just isn't fun. Especially when the expectation is that you don't use the system-provided Ruby. You're supposed to go use a Ruby version manager and set all of that up. And that rough experience can contribute to its death, for sure. I just don't think "has few commits in the last month" is a great reason to declare a project as dead, especially one providing the backbone of GitHub Pages.
