It’s obviously not enough to give up the day job, but it dwarfs all other contributions I’ve had.
As a data point, my open source web app for a casual game received thousands of dollars of donations (not remotely covering the development cost if we go by hourly rate but that’s never the goal), while my open source developer tool with a couple thousand stars on GitHub received <$50 over several years. I don’t beg for donations in either case, just an inconspicuous link.
Disclosure: I donate a very modest amount to various projects every year.
It's pathetic, and just shows that most people haven't evolved spiritually beyond being freeloaders whenever they can.
No wonder millions would rather stand in line the whole day to get free bread than pay just a little for their food.
