That was your expectation, not mine. You were led to believe one thing; I interpreted this article differently.
Sure, for some people, the title could be seen as clickbait. I didn't see it that way.
The author did present information, just not the information that you wanted. He pointed out that most language evangelization depends on technical publications and GitHub repos, and that this hasn't produced the desired outcome. That's practically axiomatic! Just look at where Clojure, Crystal, Elixir, F#, Haskell, Idris, Julia, Nim, Pony, and Ring are. They're still struggling for relevancy.
In the third paragraph, he states: "I’m a Smalltalk evangelist and Pharo is one of these languages." There's nothing dishonest here. He's presenting Pharo and the programming competition as a sample case study.
Once you dive into the linked article, you learn all you need to know about the competition.
