> Governments and all of us would like to see cancer and Alzheimer disease cured.

i think an important question is "who is this "all of us" you speak of and who made you god to pronounce it"

you are making an arbitrary distinction because vibes, because it's a cause you care about. it's irrelevant. if you take money for Alzheimer's research, you owe the government one (because that money is extracted from the people in a way you could never have done yourself). if you take money from, say a 501c3, it's a completed transaction of services.

Not sure I understand your point. Add a qualifier if you want. It is not taking money as much as responding to a request for proposals.
