As an anecdote, all of my work on open source (and I've been working on and with open source software for the better part of 30 years) has been because I had something that needed to be done and writing, adapting, or fixing open source packages was the fastest, easiest, and cheapest way of doing that. My employers paid me to get things done, not to write software. Writing, adapting, or fixing software is the means, not the end.
