I think donations is one way to go. Since I'm on Linux, I use a lot of software from people outside the big tech camp, such as the awesome kitty terminal. There was a bug in it which unreported and when the developer fixed it in less than 24 hours, I signed up to give him 10 dollars per month. About 800 other people were already signed up and giving donations (possibly smaller). People just like to give back, so make it easy to do and they will. But you need to make a product they use every day.
