The [flagged] indicator on a submission usually indicates user flagging. Moderators and algorithms just quietly downweight submissions without any visible indicator. So this isn't an HN moderator position, the question to resolve is why users would flag it.
In this case, I'd have flagged them too if I saw them. The "long live" post is an aggressive tirade that reflects poorly on the author and led to a poor-quality discussion. The second is a link to a git commit history, which is weird in its own right and provides no explanation, and the context provided in the comments shows that a generally dislikable figure with extreme political views is now leading a fork of X11 that has yet to prove itself viable. So I'd probably have flagged that one too as pointless drama until proven otherwise.
