Yes, moderators moderate this site. This has been true from the beginning, 15+ years ago.
Your comment suggests an assumption that without moderation, the ranking system would indicate "what is interesting to everyone". That assumption isn't just wrong, it's super wrong. Here are some past comments about that, if anyone cares: https://hn.algolia.com/?dateRange=all&page=0&prefix=false&so.... The short version is that without moderation, the site would be dominated by the same few hot stories repeated ad nauseum, plus an endless supply of riler-uppers. This is no way to optimize for what is interesting to everyone. As I said elsewhere in a reply to you, there are tradeoffs along every axis of this thing.
The number of attempts to either shame or coerce him into doing things the way you think should be done, versus what he thinks is appropriate -- seems childish to me.
