What a misleading argument. Yes, Apple believes that restricting IOS browsers to Safari improves security. This is NOT the same as saying Safari has fewer bugs, or fixes bugs faster, than other browsers. I suspect Apple's argument is that by allowing other browsers, and their plugin management system, the other browsers (or their plug-ins/extensions) will be able to bypass the App store and do things that are insecure. And it is hard to see how counting numbers of bugs has much to do with the severity of the bugs. Not every bug allows a jailbreak, but the ones that do are of much greater concern.
