So why not just remove the Contacts API entirely then? If it exists, "shady operators" can misuse it. Oh and, camera apps made by "shady operators" could be sending your pictures to questionable places so why not remove the Camera API as well? And we can't forget that "shady operators" could be snooping through your files so let's remove the filesystem API too.

Actually now that I think about it, any app could be malware, so let's just deal with the root of the problems and remove support for installing third party apps entirely. Everyone should just use apps made by google and nothing else, that way you know there aren't any spooky shady operators hiding under your bed.
