I completely agree. I feel like this quote in particular is intended as a personal attack, and that its inclusion dilutes the actual potentially valuable criticism and suggestions to the point that they’re basically irrelevant.
That’s a shame, because I also believe that all projects like this have room for improvement.

In context, it's clearly meant to hint at a purported pattern of problematic behavior, the specific instances of which the author is unwilling to get into, for whatever reason. While gossip is always unsavory to some extent - anonymous gossip all the more so - I think we should be respectful of the author's choice here and not take what they wrote as being by definition a violation of civility norms (as a personal attack would be).
