I don't understand why people concoct all these bizarre scenarios - in the same way that Google will never actually sell your data to advertisers - because that's what makes them money, Google are also not going to be passing video footage of you on to anyone else because again - as soon as there is the slightest suspicion that something like that is going on - people will dump Google like a hot stone.
Pretty much the same argument exists for Android - if people legitimately started reporting they were being served ads for something they were talking about to someone else over the phone - or even just with the phone (in standby) in the same room - an investigation would happen and people would start ditching Google - even before the results of the investigation was complete.
I'm surely not the only one who has common sense when it comes to this?
