It's worthwhile pointing out that many of the original Chromium developers were previously employed by Google to work on Firefox. Now, I don't know whether this is true in Ryan's case, but it doesn't seem that surprising at the end of the day. Equally, Google ultimately has an interest in the security of the web platform (as well as its interoperability), as their entire business is built on it. They'd have a far harder time selling some of their products if people believed it to be insecure.
