As I said in the opening of this post, I set up GitHub Sponsors for myself as a way for people to show fiscal support for my open source work if that's how they prefer to express their thanks (including businesses). But for me, since every commit is a gift, I'm financially secure, and I'm not trying to make a living from my volunteer open source work or put in the effort to make sponsorship worth it, I have chosen to treat fiscal support as a way of showing reciprocity for the gift of sharing my code that you've already received.
