Haskell proponents vastly underestimate the importance of stability to industrial users. Java provides some very strict promises about backwards compatibility that make it very attractive if you’re going to write a service and maintain it for decades.

Also, unlike Haskell, I can hire a huge number of Java devs, at a reasonable rate. My company alone would probably double industrial Haskell usage if we were to use it, making hiring a serious challenge.

So yes, for metrics that businesses care about, Java might be the best language around.
