That's exactly why I didn't reference copyright in my comment, even though the article itself centered around it. The word "probably" was carefully chosen as well. There are definitely things that people do that don't make money, but few of them ever reach any significant scale. The major exception I can think of these days is the Linux kernel, which famously was a "just for fun" project. Another is the GNU project, which basically exists to advance some philosophical principles.
But, to a first approximation, in a capitalist system, if $THING doesn't make money, $THING isn't going to get done at any scale which matters. There are exceptions when philosophical principles and inherent human desires (such as curiosity and artistic expression) are involved. The corollary here, in true "the market adapts" fashion, is that if $THING is done and an entity with sufficient money dislikes $THING enough, then $THING will no longer be happening. I'm not sure whether the initial statement, or the corollary is fundamentally more distasteful.
