I’ve got some standing orders of 1 or 2 euros every month for bigger projects like grapheneos and kde. And for small apps that I actively use, I try to donate 5 or 10 euros now and then. It’s not much but I believe if everyone is doing their part we succeed in the long run
None, I’m unemployed and don’t have the money to spare :3
When I still had my last job I would donate really any time I thought about it, around 5-10$ a time. Still not really enough, but it was part time minimum wage.
