Why? Why would you dislike a solution which neatly solves a false dilemma?
You may subjectively believe that sarcasm is over-used (and in fact I personally agree with you), but why are you put-out that people who like it have found a way to encode the non-verbal cues of speech into text to increase fidelity in communication?
EDIT: the problem _specifically_ with sarcasm and clarity is that it appears to say the opposite of what it actually says. You say in an earlier comment that "Sometimes people make a joke that not everyone is going to get. That’s fine." - but that is in fact _not_ fine when the possible outcome is someone believing that you hold a view entirely opposed to what you actually do. I hope I don't need to paint you a picture.
