I've been sitting on GitHub sponsorship setup for htmx, but this motivates me to get that done. It would be amazing to work on a passion project and get paid for it.
I have a bunch of projects which seem to be popular, and a lot of followers. Income received via sponsorship? €0.
I think a lot depends on luck, and the kind of repositories you manage/create. Some projects are obviously more commercially useful than others, and those are the easier ones to receive income from.
