The author is a software engineer and when he says "people", he implicitly means other software engineers. When he says "replace" he means in code, not in equations. It's a general challenge of writing on the web that you don't know what context the author assumes and the author doesn't know what context the reader assumes. In this case, the blog title "Computer, Enhance!" and the article subtitle "Switching away from radians makes code simpler, faster, and more precise." sends a pretty clear signal that this is about programming and not pure mathematics. For any given article on the web, you can always generate valid criticisms based on the author assuming some context that may not be true for all possible readers. You can't say, "Ice cream is cold" without some commenter pointing out that you're doing a disservice to astronauts for whom ice cream is freeze dried and room temperature. I find the best way to extract value from writing on the web is to simply try to understand the author's assumed context and go from there.
