If you buy apps from Play, you might want to reconsider though you don’t have a whole lot of choices. Google has been passing along app buyer information to app developers?
To what end?
So far, Google has been pretty quiet about this which isn’t a good thing. I like to think that this is a flaw but the stories about when this started happening and the fact that it could be a deliberate move by Google has me worried.
However, I do question why it's taken so long for someone to speak up. Now, if you're a malicious developer looking to steal user information or perpetuate some sort of criminal activity like identity theft, you probably thanks Google silently and go about your biz and not say a word about this.
Google has said that they could potentially share user information with magazine publishers but this is going beyond that.
