Donating is not necessarily an ethical "must", as it is entirely possible to continue being true to one's ethical principles while sitting on a huge stash of money, but from a philosophical perspective I'd say that "easy come, easy go" is as good as any a principle for releasing some of that cash towards those entities that align with one's aformentioned ethical principles. The money was neither earned nor owed for services rendered, yet there it sits, unused and inaccessible.
