@fu I'm willing to submit issues if the project has a non-GitHub mirror. I've even created accounts on small code-hosting platforms or project-only platforms to submit issues. But if I have to log into GitHub in order to submit an issue, I'm more likely to look for a replacement than submit an issue.

Even though I still have a GH account, it's been empty and unused for a decade. ( We should have learned from our previous experience, when almost every FOSS project's repo and issues were on #SourceForge. Or even from the mad scrambles when Google Code & Gitorious closed. )
