The remark about the script-kiddie able to find vulnerabilities is ridiculous for a wide variety of reasons. Script-kiddies are not able to find vulnerabilities in any kind of system. Computer hackers obsessed with security do that and (most of the times) it's not easy by any means, i.e. Saurik.
In addition, I'm not sure what Saurik, the creator of Cydia, has to do with this discussion at all.
Finally, and most importantly, you don't seem to understand the current mobile market. Most users are the end-all-be-all of end users. Many people I know think that most of the apps on the iOS App Store are developed by Apple. People install apps without thinking. Tons of personal information is stored on your phone and in these apps, such as contacts and banking information.
Google/Android is open in the sense that Android is open source, so hypothetically anyone can hack on it.
You are the person who is half-pregnant. You want the normal end user experience, where you don't have to worry about compiling the operating system yourself, but you want it to be "hackable". That is not the definition of open. That is the definition of insecure. Because most Android users are not sophisticated computer users like yourself, a hackable operating system is just a bad idea.
If you want an OS that you can do whatever you want with, and is incredibly insecure, then fork Android and have at it. Do that, instead of complaining whenever Google makes changes that you don't understand and affect your somewhat specific and not very common use case.
He has found various security bugs in Android (most recent example: http://www.saurik.com/id/19 from the other day) and he is also the developer of http://www.cydiaimpactor.com
atmosx's point was that it isn't 'skiddies' who are finding these security holes, it's experienced developers and security researchers.
What utter piffle.
That's ridiculous. Openness, unlike pregnancy, is a spectrum. And intent matters.

Script kiddie, random malicious hacker person, whatever. Yes, people like Saurik and other white hats are capable of finding these sorts of vulnerabilities, but certainly other kinds of black hats are capable as well.
Not really sure what you're trying to say here... seems like you're just spouting nonsense and nitpicking.
As another poster said, we should be taking this up with the Samsungs who ship devices with non-unlockable bootloaders.
