I don't dispute that the researchers were dishonest and broke the trust of the kernel maintainers. So they can be a bit peeved off at UMN. But is this sort of thing not the reality of their operation? That liars exist in the world? I don't really see what the volunteer part has to do with it. If anything it means they have less to complain about. I mean...most soldiers are volunteers, which would make it even more absurd, if someone signed up to be a soldier, and then whined and complained when enemy soldiers shot at him. It seems equally obvious to me, that an open network should be assumed to have malicious actors on it, as that a battlefield should be assumed to have enemies on it. Obviously you don't have to like the enemies.
