Well, adoption rates of programming languages has almost nothing to do with the features and qualities of the language itself. Swift is big because it's backed by Apple, Go is big because it's backed by Google, Javascript because it's on the web, etc. Python might actually be the only language that succeeded "on its merits" to some extent, and even then it seems more to do with some early success and libraries than the core nature of the language itself. As the author of the post, I don't actually think I can make a compelling argument for why someone should switch to using Haskell in their day job. I don't have real experience in the software engineering industry, and from what little I do know language choice doesn't make a huge difference. That said, I think it's valid to say that a given pattern is bad, or another pattern is better. I was trying to argue for that in the post in a couple cases that I think Haskell does well.
