You see, Apple's "enough is enough" is exactly, "you have CALEA, we work with you based on that, but now you ask us based on 'All Writs' to modify our products.

You see, Apple's "enough is enough" is exactly, "you have CALEA, we work with you based on that, but now you ask us based on 'All Writs' to modify our products." The essence of "All Writs" is (actual quote) "all courts established by Act of Congress may issue all writs necessary or appropriate in aid of their respective jurisdictions and agreeable to the usages and principles of law." which if I understand means in simpler English "we can officially request anything from everybody when we do our job, unless it appears as too illegal."
