I have actually authored systems at big and small companies in:
C#
VB
Pascal
Java
Python
Ruby
JavaScript
My point was not that big companies don't use languages other than Java. My point was that the tired cliche of Java dominating at big companies is entirely warranted. If I implied that Java penetration at large enterprises is 100%, then there is a lot more wrong with my writing than a missing apostrophe.
Why bother? Count the down votes in this thread and then note the number of thoughtful rebuttals. (But for the record, imo Haskell is a glorious language.)
Big companies create a lot of projects, some of them are bound to be in Java.
I in no way intended to state Java was the only language for business applications.
