These philanthropic organizations almost always have either (a) committees made up of scientists that decide where the money should be allocated (e.g. HHMI) or (b) donate to institutions which then dole out money internally as project grants that are vetted by other scientists.

Microsoft paid 2.5 billion for Minecraft. Please don't let the negativity here lessen your motivation. The negativity says more about the persons being negative then about you or your research. I believe crowdfunded drug development is a good way to evolve our society and will ask my friends to consider donating.
