Kickstarter, Patreon, Etsy and GitHub Sponsors are all very recent inventions. Heck, Youtube being a viable career is an incredibly recent invention.

What I'm saying is that I doubt that any of these are the last word on the topic. Look at how OnlyFans shook up the adult content world, and I don't think that they saw it coming.

I am optimistic that something equally paradigm shifting could occur for makers and OSS maintainers, even if I don't claim to have a vision for how it would work at the moment.
