i think dang is successful at moderation in part because he does have a reputation and track record of being fair and unbiased in his moderation, and i do agree showing bias in conversations can make people question moderation decisions more, but i'm not sure tom is showing bias by including information relevant to people he knows, and i think he can both discuss however he likes while also being transparent and genuine in unbiased moderation
tom has and does stay out of debates and in-depth conversations around HN related stuff. he's simply dropping some information in to dispel disinformation, which i think is reasonable
