> Look at permissive open source software ... No copyright does not mean no compensation
From everything I've heard it kinda does. If you're writing something valuable then maybe a company will employ you to keep working on it, and the portfolio can certainly help in interviews (to write other software), but getting non-negligible compensation for the use of the software itself is rare. Even those projects that are well funded, like the Linux kernel, are done so not out of goodness of heart, but due to companies realising it's in their rational interest to have a common standard base of sorts
In terms of written works, the best comparison we have is Wikipedia, and while the foundation does receive funding from companies who realise how useful of an integration it can be for their products, the writers themselves do not get paid afaik (and when they do, it's rarely a good thing). But if you just wrote an open source textbook, I doubt you'll manage to make much money off it, and the prospects for fiction look even worse
> Perhaps kickstarter-style firms that direct oversight over funded projects
Sounds like a return to rich patrons and needing to flatter them to get grants. Luckily with the modern internet we do now have democratised layman patronage, but why the need to force everyone into that model? Also note that almost all successful Patreon artists do have perks for paying, even if it's just early access, and afaik make a lot of their money off commissions. Those who just post art for free, with no paid comms, and just have a "tip jar" make relatively little from what I hear
