Coding isn't always compensated. Open source projects thrive because of the work of developers that don't get paid in most cases. That doesn't stop them (although it's probably because they do other work and can spare time and money).
My point is that both, art and coding, don't require compensation. Many people do both for the sake of it.
That doesn't mean they don't deserve compensation (in the form of donations). They do, most than any other.
It resembles the efforts of Archive.org and other culture-preservation driven websites/projects.
Internet is (or should be) our Library of Alexandria, where everyone is welcome —no matter their country, believes or financial situation— and have a feist on culture and knowledge like none other and for free. Games, art, books, cinema, Lemmy-like forums. You name it.
