Worse still - on iOS there's no way to block this kind of stuff. On Android there's both VPN and hosts file based blockers as well as extremely capable tools like XPrivacy for those who really want to get down and dirty.

Try launching one of the top games with XPrivacy installed. You get to click allow for the dev's server and block to 5+ 3rd party analytics, crash reporting and ad services. I'm sure many of these provide developer value, but there's definitely a harm to user privacy.
