They could rule against personalised recommendations whilst protecting recommendations where everyone sees the same thing, but logically it seems more likely they'd do the opposite (more reasonable to consider a single centralised top stories system consistently highlighting content to all its users a reflection of a "publisher" preference than an algorithm which highlights content based on each individual user's activity and filters the individual user may have set, moderators tend to manually intervene to influence the former more, and of course it's less reasonable to demand that all potentially libellous content is screened from procedurally generated individual user links than from a "top stories" list or home page.) I think most of us would notice the difference if HN was allowed only to rank comments only in chronological order, never mind if for liability reasons the stories permitted to appear in order of upvotes on HN were restricted to the ones Dang was satisfied weren't libellous, or possibly none at all if YC decided it wasn't worth the risk
