I'm unbiased towards the subject. I'm genuinely curious about how long-term FOSS ideology would work.
I'm using FOSS but I'd still consider myself a casual user. It seems like most FOSS I've seen is a free, buggy, alternative to mainstream software, which resolves a problem the user had.
From my perspective, (and do correct me if I'm wrong) FOSS doesnt seem sustainable. Everyone can contribute, but how do they make a living? My guess is they do other things for income. And what about the few contributors who do 90% of the work?
What if every software became FOSS? Who would put in the free labor to write the software to print a page, or show an image on screen, or create something more complex like a machine learning advanced AI software?
Would it simply be that everyone provides for each other? Everyone pitches in? What about people who have bills to pay? Would their bills be covered?
This concludes my right-before-bed psychology inquiry.
There's no single goal to FOSS. I write software for my own needs, and it literally costs me nothing to give it to other people. It makes no difference if I give it to one person, or one million, or one billion - it's no harder, or easier, than giving it to no one. Other people seek recognition or the approval of other people. There are probably as many goals as their are FOSS authors.
Financially, you either try to support yourself by soliciting donations, but that just makes it work, and - for me - imparts a sense of obligation to my users. But, yeah, most people have other jobs.
