There's this WP article https://www.washingtonpost.com/technology/2021/10/26/faceboo...
where they bend the truth. The headline is "5 points for an angry emoji, one for a like", but in reality it's 5 points for any emoji at all, and one for a like. Which I think makes sense, hitting like is something that's automatic for a lot of people, whereas taking the time to select an emoji that most closely matches your reaction to a post is a much more "engaged" interaction.
