I really think the developer community needs to learn the age-old skill of ignoring things. Don't treat things like dependabot, PRs,stars, issues,etc.. as a metric or quantifier of how good of a job you're doing with your code. Forget that social-drama nonsense.
I think the bigger problem is that Github is being treated as a quasi-social-media, and these things are being viewed as a "thumbs down" or "dislike" (and vice versa). Unless you have an SLA with someone, you don't have to meet any numbers, just do your best when you feel like it, and drive your project best way you think. Just don't be a dick to people about it, or react to these social-media metrics by lashing out against your users or supporters (not claiming that in this case!).
