It’s just a title to a web page meant to be interesting. Regardless, he didn’t represent himself as a teacher. He didn’t teach. He represented himself as a curator of a webpage, and the tittle of the page I don’t think it meant to be misleading just compelling. It’s a bit of a stretch to take it any other way, and a shifting of the goal posts. I think if you agree he didn’t do as you said he did, it isn’t self diminishing (after all the self is an illusion!) to simply state there was a misunderstanding.
