And there's the time someone did try to sneak something into an open source kernel [1].

The cool thing is, anyone can audit the kernels any time, and even if Theo's or Linus's accounts get compromised, the backdoor will be observable by everyone.

Try that with Windows: we have no idea what's in there, we never will, and MS has zero incentive to tell us.
