We can consider it incomplete, or disagree with the design choices, but broken means it doesn't do what it's supposed to do. Here, it does everything the author intended it to do, and everything the description says it does. When you say it's broken, it sounds at least to me like you're imposing your own requirements on a project you have nothing to do with. It's like calling Microsoft Office broken because it can't handle Open Office files. It's not broken, it just doesn't have all the features you would have included.
