Would they individuals that donated 10M for this have donated it if it was for affordable housing instead? furthermore, do they only donate to this cause, or do they donate to other, more social causes? how much affordable housing can you actually build with 10M? is it immoral to use money in anything other than affordable housing?

If it makes you feel better, one of my friends does fundraising for the arts. As a liberal, he hates that he needs to be surrounded by Republicans at fundraising events, but he says it's the only way to raise money, as Democrat donors are completely uninterested in donating to the arts: they all want to donate to feel-good causes, like the aforementioned affordable housing. Meanwhile, Republicans are more willing to donate to the arts (which is kind of unsurprising seeing how a lot of rich people use art to store value, if not outright to launder money).
