I think you just covered it. Are you doing it for the money? You may be
honorable enough to not cheat, but that isn't saying that everyone is. I
think it is prefectly reasonable for distributed.net to ask us to trust
them. After all, we are running their software, so we already have to
trust them to some extent.
But anybody can grab their software, and use the their labor to come up
with a solution with no effort on the user's part other than processor
time. Sure, it would be nice if we all could be trusted, and in the
perfect world we could be. But it ain't prefect.

Probably. But why risk it?

Come now. They have to verify the validity, obviously. That doesn't take
to long, but they certainly aren't going to say, "We will award the money
to whoever announces that they broke it first." And it doesn't matter
where the money is going to, it still will take some time.
