Cory's original usage of the word gave it a useful and specific meaning. But that has evolved extremely rapidly with popular usage into the word simply meaning "I don't like this thing." Which takes away the usefulness because now it's no longer describing a specific reason for not liking it.
It'd be like if every kind of ailment started being referred to as an "infection." Concussions, sprains, hypothermia, etc, all being passed off as "he got infected." We already have generic terms for that like "he got hurt," and now when someone does get literally infected we've lost the word that would be used to specify that.
Languages evolve, sure. But that doesn't mean it's always in a good direction. In this specific case evolution is enshittifying the language and that's worth a little (admittedly futile) push-back.
