> Do you have proof that they are "in the process of leaving twitter"?
The point being here, that you are being pedantic, and borderline bad faith.
It is perfectly reasonable for someone to say "Hey, there is this person who is leaving twitter", in reference to a post of them saying that they are doing that.
And you are coming in, saying "Well, actually! Technically speaking, I don't see a deleted twitter account yet, therefore by the laws of debate land, you are wrong!" just comes off as you being a pedantic idiot.
The original interpretation, is a reasonable one, for regular human beings to reasonable agree is mostly true. And pedantic "well actually" people, like yourself, are contributing nothing to the conversation, and just trying to get a 1 off, bad faith gotcha on a technicality.
Stop. Nobody likes you when you do that, and nobody is fooled by your behavior.
