Dude, chill, you're way too mad. They didn't said guide should be removed "as quickly as possible", it's just that wiki is more official source, so the guide is becoming unnecessary, especially since the wiki is updated constatly and regularly. You said it yourself that updating the guide is not worth your time. Why are you so angry then?
Also, I don't see why are you so angry for the "I'm sure" bit. You're overinterpreting it, he just said that it was a great help to people, how is it condescending? It's just that the guide is getting more and more irrevelant
