My favorite thing about free android apps is how so many demand access to contacts and location (and sometimes microphone and camera!) despite never really needing them to work. Since most people have no idea how to deal with this, they are paying a much heavier price for those free apps than they think. At least the newer android versions let you revoke these permissions, but given the state of android version deployment, it seems likely the vast majority of android users are giving quite a lot of personal information away to quite a few people.

It was not the sole reason I moved away from android but it definitely helped me make the decision.
