The way I see it, he (and any other maintainer who chooses to do the same) is perfectly within his rights to do this. They're his projects after all, it's up to him how to run them. That said, if a contribution of mine is ignored in a project (and a few have been), that usually becomes my last contribution to the project. Afterwards, I often choose to instead invest my efforts in other projects. Ultimately, by Linus's law, those projects that accept the most contributions and/or foster the most active communication ought to raise to the top. I think that we simply can ignore back the projects that ignore contributions; they're the ones who end up losing out, as far as I've seen anyway.
