Like/dislike is not structured feedback. The most awkward situation is when people "like" some tragic article. In this case, Reddit and HN do better - you up/down vote, you don't "like". Instead, they should've added multiple "reactions". Like/dislike, agree/disagree, boost up/down, etc. Of course, the equivalent of "upvoting" possibly is "sharing", but often you don't want to pollute your timeline, just to boost the visibility. I think Facebook is making things worse, not better.
