If you only care about the bugs that someone else fixes for you, then you don't actually care. They do, and you're just pretending. It's perfectly reasonable to stick your fingers in your ears and go "LALALALALALALA" instead of listening to reports about bugs in your product the moment you stop giving a shit about it having bugs. A competent person who actually gives a shit isn't willing to put their head in the sand like that.

You're mischaracterizing the author's post. Notice that the author specifically wrote:

+ "Fork the repo, add a failing test."

+ "Add an example in the repo that illustrates the bug."

Neither of those requests is "fixing" the bug for the author. Maybe those tasks in your opinion is asking too much of users -- and that's fine to feel that way -- but it's obviously false to say that submitting bug reproductions actually fixes the bug. It certainly doesn't.
