I don't necessarily agree with Myhrvold, but I don't think this guy is giving him enough credit.
The problem Myhrvold gives is real: large companies with lots of resources can, if they choose to, steal your idea and try to compete. This problem comes up on HN periodically, and I think the canon is to simply have the better product. I would call this playing field more level than the one where entrepreneurial teams can't compete at all.
