While I don't condone some of the treatment he received, that situation was extremely different.
A user reported a safety issue, the maintainer said it was safe. Then it was proven that it was in fact unsafe, and the maintainer justified it with performance. Then a PR was filed which was safe and did not regress performance, and the maintainer rejected it with "this patch is boring"
The behavior of both sides was deeply unacceptable. If someone identifies a legitimate issue and files a PR to fix it, don't insult them by calling the patch "boring" and don't reject it solely on that basis.
