So basically, google knows that you are cheating on your partner like.. when you go out at night time and you will see other women and you will be in airplane mode so that your girlfriend cannot call you.. Google will know. Hahaha that's cute.
I might be a minority, but none of this has every really bothered me. I understand some people really value their privacy, but as long as I don't see a physical body staring at me through my window, I am not too concerned. I do understand that this can leave us exposed to people with malicious intent and I can see why both sides act the way they do though.
Yes, this has been going on a for a long time. They seem to be more transparent about it though because you can actually look at your history and choose to delete it now. But this is not something that is new. Facebook does the same.
