Real revolutions today have to be quiet. Besides NLnet, which I personally find trustworthy, and to which anybody can try to apply for funding, there's also Linux and FreeBSD. Those are real techno revolutions, but I'm optimistic that they can be taken to the next level. (2% support)
Be the change you want to see in the world, like Gandhi says. It's simple, though not easy. Join NLnet, or contribute to F-droid, or work on reverse engineering advanced proprietary tech. Find and learn and think about how revolutionary tech orgs are run. Most important thing to learn: how they can survive on support from only 1% of humanity. Thinking like that, it's actually easier now than any point in history.
(In another sense 1% is already a sweet spot, see

World domination is a bug not a feature. The Linux kernel is the revolution. Desktop Linux is not)
Now there are 2 ideas that I have: One, to raise more awareness about open source and how it has some gems. The best low hanging fruits of privacy for the world might be f-droid, signal (doesn't require any specific hardware as long as they have android) and grapheneos(depends if they have a pixel)
But that being said, I thought that if I share about open source and how it can be good but it requires your funding to fix the chicken and egg problem. People would feel convinced to donate.
I might say them to donate to nlnet. But I don't think many people would.
I don't think open source needs an evanglist or somebody telling somebody else to do something. I am deeply pessimistic about the state of open source in the sense that it's out of my control and my trust of human society is eroding day by day.
Literally nobody I talk to makes me feel like something can be done about this and I doubt it so much now. I was so much optimistic about its future but I am genuinely pessimistic now and the only reason I try to be hopeful is that I don't want hopelessness. I don't want to sit down and watch but fucking hell, the world sure damn well wants me to.
