Rather than donating 5-6 figures, what about saving enough cash to live on? Roughly speaking you can "make" ~$200k/year on $5M in T-bills. You could live comfortably in the US or Europe, or basically like a king anywhere else in the world. You could work on the software you want, even pro-bono, and walk away any time. I believe this is called "F U money".
