I do it by working for Canonical. The vast majority of our projects are open source. Yes, Canonical's application process is very long and thorough, but it's a good company to work for. Those aren't "my" projects, of course; I'm still very much working for an employer, but it's nice that our development effort is in the open and freely available. I also maintain a few of my own open source projects, for which (via GitHub Sponsors) I get about enough for one coffee date with my wife.
