That's not the point - McDonald's has 40000 joints - the most popular restaurant in the world. Still doesn't make it the best food option.
Yes, Emacs is not popular, but if you look deeper, you may find unsurprisingly that most Emacs coders are strong developers. That correlation isn't coincidental - you don't stick with Emacs unless you're willing to learn; it effectively teaches you about Lisp, extensibility, and programming in general.
Yet, they are not talking about general popularity of editors among devs, but about people who ever tried Emacs - the argument is that the majority of them try, fail and abandon it. For which obviously there's no polemical (or otherwise) data points.
