If you donated to me, it was sent to a charity, likely Special Olympics or a Homeless charity, as I have done with nearly every penny that has been sent for a donation (I have bought my kids pizza a few times, when the donators told me to spend it on my kids).
A minimum donation makes no sense, at that point it isnt a donation, if there is a minimum it is a purchase. Funds from SunShine go into further research, it funds our research. We still continue to release some things for free, somethings we put in sunshine, but publish details for free (No one has bothered to implement and release these for free, why? it is expensive and difficult to do so).
If SunShine ran on donations, we wouldn't support over half of the devices we do. Especially newer HTC and Motorola devices, these models required purchasing many devices for R&D.
If you think donations make up enough to fund such a project, then I suggest you try it. Watch as you spend $2100 on a phone (cough LG G3, had to buy three of these stupid things to get it done), then receive a small fraction of that in return (not even enough to cover 1 phone).
Regarding your wife, if you have to justify a $20 purchase to her, I don't know what to tell you. I know I don't police my wife's purchases, and she doesn't police mine.
Funny how entitled people expect us to invest thousands of dollars, and years of our lives for them, to never ask for anything in return. I know when I want my roof redone, I paid for it. When I needed a cedar tree cut down, I paid for it. I know when I want someone to spend time and money to do something for me, that I am going to pay for it.
If you don't want to pay for it, don't use it. Do what we did, learn from the ground up, and do it yourself. We have published A LOT of FREE training material, vulnerabilities and open source exploits, that you are welcome to review and learn from. After you spend your hard earned money on things like IDA Pro, and phones, you can develop your own sunshine alternative and release it for free.
