I think its because the baseband processor can access the microphone, screen and RAM semi-directly so its pointless having any encryption when you can just "key log" the screen as the user inputs the message. Please someone correct me.

(I posted a sort of question below along these lines but not yet had a response)

Basically, baseband can read the RAM. If you can ram dump you can do virtually anything, including get encryption keys.
