Scala is certainly worth studying for a bit (like most languages, I'd say), you should just not plan on being able to use it professionally (like most languages).
If LinkedIn is any indication there is absolutely no shortage of open professional Scala positions.
Like every language, Scala has strengths and weaknesses. It makes sense for some teams and not for others. Why don't we debate how its strengths and weaknesses can best be managed and understood rather than just pointing out one company that decided some aspect of the language didn't make sense for them.
