I'd like to comment here that issue trackers are tools for maintainers, not for users. A maintainer doesn't owe you any response to issues, nor do they owe you any way to report them. The maintainer has the right to stop working on their code at any point and completely take it off GitHub at their own discretion, should they want to.

(If you think that issue trackers should be for users to be able to tell each other if they've experienced the issue too, then that's part of the problem with "+1", "Me too", "fix this please", and other useless comments. That's what a forum is for, and today they're super-easy to create. You don't even have to host them yourself, nor do you need to be affiliated with the project!)

Lesson: if you don't trust the maintainers, you can't trust the software. Keep your own fork and issue tracker if this is a problem, but don't force maintainers, many of whom are not acting in a professional product management capacity, to do extra work for your benefit.
