Although it's not strictly relevant to the current debate--that is, the merits of this distributed computing effort--I'm troubled by both the original post and many of the replies. The original post gripes that this is for a "for-profit" company as if that is some sort of heinous crime. While I admit that there are legitimate and useful debates about the pros and cons of capitalism, last time I checked, most Western nations are, in fact, more-or-less capitalist.
I shouldn't have to point this out, but it's OK to make a profit...
Secondly, while it is true that some drugs are very expensive, it is useful to look at some of the history. Health care in general has extended lives, has in fact been made accessible to all (OK, there's some debate about how fair it is and how well we are doing, but that's not the point here.) Life spans are increasing, quality of life has increased, and so on. Obviously, we're doing something right. (Maybe we're doing some stuff wrong also, but lets have a little more reasoned debate, please.)
I have no particular position on the merits of this particular screen saver, but I'm not sure that bilious rhetoric in the original post was very well founded.
