We all know that Apple doesn't follow their own policies pertaining to the Apple Store very well. That is why this could possibly be an issue if Apple seriously enters the gaming market to compete with the likes of the DS (which many bloggers are speculating).
Apple has set a precedent for itself, apps that duplicate, or in some cases have an icon that simply looks like an Apple icon have been and will be denied.
It is logical to assume that based off of Apple's history, the same will happen for games IF they choose to enter the gaming market seriously and/or have certain games installed by default.
Many of these phones that are being sold are the official, "Google branded" version.
That means Google has certain deals in place with the carriers.
Also, they are making Google search and there other properties default on Android, no matter which way you put. They make more money if you are using an Android device (Google is embedded everywhere in it) unlike other platforms.
This DOES make them an anti-trust concern.
Google Voice is also provided for free as well, and guess what. Google Voice is getting investigated by the FTC.
