The Bill of Rights means more to me than any inconvenience I may have from my long, complex password on my iOS devices. I'm glad these changes are being made.
Let us just remember, the Bill of Rights protects you against "unreasonable" searches and seizures.
With probable cause, and a valid warrant, the search is not unreasonable.
Also. You have no "right" to keep private:
1. Evidence of a crime
2. Evidence of national security
If Apple sees a business model in creating an unsearchable tool and marketing it as useful for committing crime, let them. However, they will not get away with calling that patriotic. Too many people understand the law, and will expose the profit driven motive for what it is.
