My yearly spend is approximately €500, give or take a little. Fortunately, I can afford to do this. I hold no judgement for those who are not in a position to do. My only motivation for contributing financially is to ensure the free, functional, ad free, privacy preserving software I love continues to exist. It needs to exist especially for those who cannot afford to pay a corporation for proprietary software. A shout out to all the developers who adhere to FOSS principles. Each new year I make a list of the software I've mainlined and similar to the article I allot an amount to each one based on my usage. Many times it's time-tested old-school tools, but we're seeing a lot of new development with Rust apps, crates and TUIs. This year I added Matrix. Also EFF, despite not being directly impacted by that jurisdiction. They truly are holding back a giant wave with global repercussions. It's not always easy to justify the time spent creating FOSS tools when there's bills to pay, mouths to feed. Thank you - You know who you are.
No public list, sorry. I'm willing to say that I already support many things on your list. And like you pointed out, many projects with software I use don't have a way to support them financially, which frustrates me to no end.
