It's in the intent. I don't think anyone is denying that Apple and Google are doing this to make it harder for police to search through user files. They could have implemented this at any point since the inception of AES, and are doing it now because of the backlash against PRISM. They want to demonstrate to users that they care more about them as individuals than they do about their role in a democratic society.
Notice also that your comment, and others respondents to me in this thread, are not disputing my actual point, i.e., that bundling crypto features in products is meant to put individuals above the reach of the democratic legal system.
