re: Apple Excommunicates iOS Cracker
From the few details given in the article, he only made one mistake by failing to disclose the proof-of-concept app that he made and had passed through to the marketplace. Otherwise, he, apparently, disclosed the bug to Apple which should, in my mind, be paying him and giving him job offers for finding it. Sure, he didn't keep it "under wraps" like they always want, but hey, they can now address this serious bug, which in the wrong hands could have really made Apple look bad given their persona of it always working flawlessly all the time with no vulnerabilities. Treating him like this will probably just make things worse for them, should he get disgruntled and turn malicious. He already has a good history of finding seriously fatal flaws, what if he's upset enough to take the black hat route next time he finds one? Sometimes it's better to take the "high road" and admit your deficiencies as opposed to always attacking those that bring them to light like they are the ones in the wrong.
Yes, he could have probably handled it better and disclosed what he was planning before he did it, but in that case, I'm sure they would have just shut him down before he could have had a chance to test and release it, which is typical Apple. They would rather squash and silence it than admit there's a bug. This would have left it open for more malicious people/groups to find and exploit it for real, with real world repercussions. So, they'll just punish him instead of taking the time to learn from him or offer to let him teach them a thing or two because, God forbid, something bad is disclosed to the public about anything Apple related.
In addition to that, public disclosure of bugs should keep Apple's programmers from becoming complacent with the idea that everything they make is bug free. As a programmer, I know that the majority of code out there has vulnerabilities, I find them in mine, and if you're confident that your code doesn't contain any, that's when your most likely to introduce them or let one slip through...
My personal opinion: Give that man a medal and tell your QA department to make him an offer he can't refuse.
