Newflash: I don't give a shit about how hard your job as a programmer is. If you don't like programming take up something else. I care about my security and not having to worry about what effect clicking "OK" is going to have. Plenty of apps ask you things that they don't need to function.
Facebook provides value and poor, lazy anti-security undermines that value and puts me in the inconvenient position of thinking of a move [1]. And for what value? So developers don't have to write a switch statement? Seriously?
[1] It's not as simple as "just take your business elsewhere". The only purpose of facebook for me is connecting with friends and family. So going while they all stay is rather pointless. Getting other people, who have a different circle of friends/family, to move with me would be practically impossible.

Giving the user choice about whether or not they want to give up their personal information is a great idea. Suppose I don't want the app to have my email and phone number. Without finer-grained control, my only option is to say no to the entire app -- so they lose me as a user.
