I can get behind anonymous donations. After all, we vote anonymously, anonymous speech is protected speech, so why shouldn't anonymous donations be protected as well? In the marketplace of ideas, shouldn't it be the ideas that are judged and not who said them or who paid for the ad?
At the level of donation in this example, that probably works. Consider though a donation of say, $1 million. Is it important to know who donates that amount and thus potentially exerting a great deal of influence?
Maybe the notable difference is that while votes are anonymous, every vote is equal.
