This research implies that the linux team should not be operating on good faith.

A software as critical as linux should not be this easily compromised by a bunch of grads..

It's one of the core technologies of our computing.

Having a discussion around the ethics of this is great but it does not detract from the importance of bigger issue.

Hey, if people who rely on open source software really believe it's critical, they are more than welcome to hire engineers to audit every line they use a dozen times over. You could find many interested and capable people on this website. But the fact is a great deal of computing (and really "society") runs on an assumption of good faith, and it's just not an interesting discovery that anti-social behavior pisses people off.
