Because "coding" was what was being discussed? Not everyone understands exactly what a Dev is, or a Jr. Dev, or an Apprentice Dev, or a whatever that particular company decides to call their levels of dev/coder/engineers. Some people in the QA department are given small menial tasks to fix, they aren't a dev, what would call that person?
If I am in QA and given a task to fix 3 packs of gen pop in an instance on my own time, what would I be called?
