it would be great if the news organizations that are capitalizing on advertisements on boston bombing articles, would donate those proceeds to victims.
You could look at another way: If the service didn't exist, many people would likely not know the news, or the extent of it -- and so might not be compelled to donate or otherwise help out.
If one had to choose between news service A vs news service B, knowing that choosing A has the implication of assisting those in need, people are going to choose A.
Call it pre-emptive humanitarian news campaigning.
