It’s probably predominantly because of the switch to mobile computing / smartphones / web being dominant, and everyone referring to programs there as “apps” / applications.
i.e. If you write a mobile app with a function-as-a-service backend, you will never compile what someone would refer to as a “program”, so calling yourself a “programmer” (as-in, someone who makes programs) feels inaccurate and a not helpful description for people. “Coder” (as-in, someone who writes code) is a vaguer in terms of the type of code you write and more accurate in terms of what you spend your time producing.











If you’re a user who grows up using one, and then starts following instructions on how to build one, when are you going to come across the word program?
It will be app, maybe application, saas software, functions a service, compute as a service etc etc. Hell what most people think of as an “app” is really a collection of applications all working together.
