Depending on their opinion it could be
- Because they prefer a fancier shell that isn't bash
- Because they prefer their shell scripts to be in standard POSIX Compliant shell language without the bash extensions and features
- Most likely answer that bash is pretty good for hacking some stuff together, but not great for larger long term maintainable projects versus other programming languages.
I think it's fun though, and I'm not going to be the one maintaining it 😛
