You could have cloned, made proposed changes to the source, pushed and made a pull request. Then, referenced it here, made the same point and provided the solution with the same amount of effort as your English-only criticism.
The point I was making, albeit poorly, was open-source is awesome. git, github and pull requests make it even better.
When someone contributes something that may be half-baked and someone else comes along to critique it. A pull-request that demonstrates the solution can be an equally efficient means of communicating the same criticism. Meanwhile, the whole community reaps the benefit of that effort.
TLDR; OSS devs should favor, "showing the way" and github makes that easy.
