I understood and respected Apple's position to not aid in weakening their encryption or provide a 'Master Key of Unlocking', even to aid the FBI, in order to avoid undermining their security.
I also feel for the FBI's strong stance to force Apple to help them solve crimes despite undermining Apple's security in the future.
All I can say now is that Apple can't expect the FBI to give up how they did it on the grounds of solve a possible 'security flaw.'
Apple didn't help, so the FBI went another route. Now that the FBI got what they wanted, Apple can't expect to them to blab on their success.
