A lot of people (like myself) have a perverse interest in writing utilitarian code and building cool things and reading about how to do it all better (if not the best), in our spare time and for its own sake and because it’s fun and cool. Even though we have a “real” job or whatever. Like if you’re contributing to OS anything as a way to get rich you probably need a supplemental business plan with some serious thought put into it. I can’t help but think the author is making very good points but it assumes a different perspective or motivation than many people approach “open source” with.
Kind of like the difference between people who fell into getting paid to program because it was easy money (what, people pay me to play with legos??) vs someone who goes into a CS program because they heard one can make a good living doing whatever’s on the other end of such a degree. Very different attitudes on a passion vs job kind of level.
