Though this is a bit foil-hat for most people it can be a real privacy concern. Can your mac be used to secretly spy on you? Absolutely. Has apple done this before to their customers? 100% (and so have others) see carrier IQ: http://en.wikipedia.org/wiki/CarrierIQ

If something like this bothers you theres no reason you should be using any closed source software at all.

It's that easy. If you're concerned about your privacy and system integrity don't use any software from a source you don't personally trust and that can't be reviewed by a third party.
