The main thrust of this rambling article seems to be that Google Maps and location services more generally might not be misused by Google itself but instead shown wholesale to a third-party concert app which then leaks it to my "creepy stalker ex-boyfriend." Is there anything new in this article or rehashing familiar hypothetical scaremongering? Not saying that handing over data, especially very personal data, is to be taken lightly but this article adds nothing interesting to the conversation.
Edit: it's looking like the hypothetical sharing of your data with third parties is a fabrication from this article. Can anyone show how this sharing might happen?
