No, it’s being driven by the lowest common denominator for engagement, which is distinct from personal preferences.
For a self-contained example, spam in large Facebook groups always rises to the top, because many people comment asking it to be deleted, causing the algorithm to show it to more people, some of which comment, until a moderator finally kills the post.
These kinds of side effects do not happen in a voting based system or a straight chronological feed.
