Notably, unlike many organizations that accept bitcoin, Apache is taking bitcoin directly, and not instantly converting to fiat. They plan to pay vendors in bitcoin where possible, and convert the rest to fiat.
This is actually a great application of bitcoins, because you don't really need to know anything about the donator. An address or QR code is all you need (no registration, specifying email address etc.). And an extra benefit is that you can see how much they collect.
