I'm confused then Mr. Cook; if security was not the reason for the iCloud breach, then why beef up security? (/end sarcasm)
Reminds me of the iPhone antenna gate issue when Apple basically said there's no problem (you're holding it wrong) and then proceeded to issue out free iPhone bumpers.
To you Apple haters/MS fanboys (I am a Linux guy, but I support an enterprise environment comprised of Ubuntu/Debian, various flavors of Windows and also OS X workstations and servers on a daily basis):
What would you EXPECT from any large computer & software manufacturer in the wake of a major digital security breach? Your answer should be 'beefing up security! Oh, and maybe even an official announcement with details!!' Even if Apple is lying, and the breaches WERE the fault of bad security software, and NOT just bad security practices, don't you think it's in everyone's best interest to make security updates a priority?
Also, don't forget the years and years of MS's 'dows getting hit left and right thru security vulnerabilities in its built-in software. Android has also had its share of security breaches - you can even Google it, if you feel so inclined.
