Regardless of the specifics of this case, I do feel like there is such a thing as "burning out on open source", a topic which is of interest to me at this point. I would like to read other people insights about this, this would probably help me better at setting proper boundaries in my own projects.

I found myself often struggling to deal with this kind of issue: How to be sure whether you are being used (possibly not even on purpose), or whether the issue raised really benefit the whole project?

On one hand we don't want to be used, on the other hand, we don't want to chill contributions of good ideas. It can be tough sometimes to assess properly (keeping in mind we all have bad days on top of all this).
