I didn't read the terms, so I don't know.

But a fair system should be that the App owner should decide what ad network to use within its app.

The argument that Google doesn't allow Yahoo ad to show in Google search result is invalid, because Google search is entirely owned by Google, so Google can do whatever.

I don't think Apple will be so stupid as to kill AdMob. A lot of free apps depend on AdMob to make money. Without AdMob, those apps will die, and that will be bad for Apple. So, there is no way Apple will kill AdMob.
