The secret of Scala is that it can be used in a wide variety of ways by a wide variety of teams. Yes, you can end up hiring people that would rather work in Haskell, or those that hate the type system and would rather code in Clojure. I've seen people that attempted to make Scala look like Java, or even Javascript. My current team, working in Scala, has had plenty of people like that. But the fact that you can get too academic with Scala does not mean you have to.

Some parts of our codebase really work better with said academic style, so we keep them. In others, the type system was used in ways that did not make any sense, and were rewritten.

Scala's strength is precisely that it can look like anything you want. If you are not interested in said freedom, then sure, avoid Scala at work. But for us, using the style that works better in each part of the system without actually having to change languages is extremely powerful.
