Consider that content can have way more potential to be educational and interesting when crafted with a specific audience in mind. For an Elixir post, that audience need not be "all programmers". I see nothing wrong with the author's approach and would gladly welcome more writing of this style.

Perhaps what you mean to say is that you'd like to see more folks in your own communities writing about Elixir with your relevant needs and perspectives in mind.
