What happened to reactions?

Personally I disagree as I think some nonstandard reactions can function beyond a simple “like”. For example, I often use the “thumbs up” reaction to signal an acknowledgement, potentially an agreement with a statement, but nothing as strong as the heart/like reaction.

Further, even if I did agree that removing all “negative reactions” (how are we defining this) I disagree with the current implementation, in which some posts appear to have multiple likes from one user, because the “negative” reactions are still counted in the in the like summary, but the user who gave a previously negative reaction is no longer visible in the reaction list on the post.
