@danderson arguably the badness was stopped because professionals noticed something fishy and found the root cause. If anything, to my mind, the system (if it can be called one) is actually working quite well given the fallibility of humans and the systems we create.
@piecritic Yeah except we didn't notice because of any kind of intentionality or process. It was blind luck that the right someone got annoyed at a tiny change in performance and went digging. If that one person had been on vacation for a couple weeks, I could see this shipping to a bunch of enterprise distro releases before anyone caught on. Or even nobody noticing until the first high profile compromise that used the backdoor. We got very, very lucky.
