This is what I figured. My experience of SW development at a merchant bank is siloed teams using their own development tools to support their banking operations. There was never a company wide mandate on using/not using some technology. |

There are like 3 to 6 major platforms used inside of JP Morgan, depending how you count (the oldest one is deprecated and being migrated away which will never complete, while the newest one is nowhere near working and will not have anything running for a long time).
The largest one regroups maybe 30% of all the developers and developments in the firm.
The Perl system was underlying on of these platforms, and has clients for use in all other platforms, so it was quite ingrained across the entire company really.
