Give then context of the conversation I think the company was limited to one team or perhaps a few. Even within a larger company multiple languages limits the effectiveness of Human Resources. You can't as easily move people between teams.
That doesn't matter. I've worked in large insurance companies that had SQL procs, Java, and Old Cobol. They had over 1k IT employees across the country. Sure there are odds and ends in bash, but bulk of the core business systems were in Java.
