That’s weird, because it also has 2 downvotes for me at the moment (which means it can’t be some weird federation issue), but assuming that you originally saw 2 downvotes before I came along, then something something can’t be right because I am one of the two downvoters and I only saw the comment some hours after your comment in this thread (judging from the timestamp of my comment) (or maybe I visited the post once, then came back to leave a comment?).
