I personally think that the Goog has finally crossed the line from innovating to protecting it's territory. A couple of examples would be the sudden killing off or as they say "retiring" of Google Reader. And they aren't making any friends with the sudden banning of most ad blocking apps in the Play store. According to Google, the apps cause "interference with another service or product in an unauthorized manner." Since ads are the biggest share of their revenue.... makes no sense (in their eyes) to block them.
