I think the tweet is pretty clear on its intention for the definition and I’m not interested in arguing about it.
I do think the dictionary definitions, such as they are, are coming from a real place: some people do use the more general definition. And you seem to already know about both definitions. So why argue so belligerently and definitively in the first place? Parent comments you were replying to were obviously using the original definition. Talking about “retconning” is obviously silly given this timeline. Meaning in language is not a race to be the first to make it into a dictionary. It’s a very new phenomenon that new terms make it so quickly into a dictionary at all, and they’re always under review. So maybe factor that into your commentary?
