Those old articles shows us that Apple agreed to join the PRISM program. And it´s not that strange that they are trying to deny it after it blew open.
Two step verification and other security features are nothing if Apples attitude is that it is ok to break users integrity.
I have also minimized my use of Googles services for the same reason I´m now minimizing my use of Apple products. They may be good at making great products, but if they sell users out, I have to show my concern in some way. I think more people should do that.
I do not believe they are part of PRISM or any government program at this point and have closed all back-doors. I do not believe, from what they have stated publicly, it's okay to break user security. Tim Cook has stated that humans are their customers, not their data.
