When open source was becoming a huge thing for everyone to participate in - say 20ish years ago, I always saw a dichotomy that people seemed to gloss over.

You're either writing software for fun and you are happy to give it away. In which case anyone's use of it is to do as they please including make money is just bragging right for you.

Or you write software for a living in which case giving it away for free is dumb. You want to charge maximally for your money making output.
