http://www.telegraph.co.uk/technology/apple/8912714/Apple-iT... is a story about how Apple didn't fix a remotely-exploitable bug in iTunes for years after being notified about it. During that time governments were said to have used this bug to infiltrate users' computers.
And the worst part of it all: The majority of Apple's software (certainly both FaceTime and iTunes) are proprietary programs -- user-subjugating software that does not respect a user's freedom to run, inspect, share, and modify the program. This means that even the most skilled and willing users are prohibited from fixing the problem and distributing a fixed version of the program to help their community. So, rich or poor, proprietors do their users a disservice by distributing proprietary software.
