This is just a hiring problem, not related to functional programming. I agree with the basic premise of the article however: depending on the financial condition of the company, hiring people who are overly attached to or obsessed with a single technology probably isn't a good idea. But that's of course not exclusive to functional programming. Right now you will find plenty of people obsessed with Rust (not a functional language) who don't care about the business goals and only want to write Rust. A few years ago it was Go. Before that it was Node.js. A few more years ago it was Ruby on Rails.
