To really understand this is well beyond my pay-grade

Your Computer Isn’t Yours

Bottom line … Apple are tracking us all - in a very sneaky way …

โ€It sucks that theyโ€™ve let the NSA, CIA, your ISP, et al slurp up this unencrypted pattern-of-life data off the wire for the last 2+ years, and theyโ€™re still going to transmit the data (encrypted) to Apple in realtime, on by default every single mac, but at least the 0.01% of mac users who know about it now can turn it off, so Apple will only get a realtime log of what apps you open, when, and where for the other 99.99% of mac users.โ€

Anybody shed light in a simple way?
