Because the C?I?A? and N?S?A used to use pre-OSX mac computers extensively at the time that M-Soft got sued by the DOJ because there were a lot less OS8 / 9 hackers than their were window hackers. Then by some funny coincidence, OSX gets based on UNIX so now any government hacker anywhere can hack into your Mac with the greatest of ease. Why would you want to rock that boat if you were the government? You wouldn't. You'd say, "As long as you keep making it easier for us to spy on people, you can bundle anything you'd like."
