Actually that's still bullshit from Gruber. Google may have made a touchscreen OS but they still deferred to Apple in many ways, most notably by not including 'pinch to zoom' and other UI that Apple claimed was theirs alone. Google stood by and watched as Palm jumped into direct competition with Apple and included that, lawsuits be dammed.

Apple broke the peace when they rejected Google Voice from the AppStore last summer (and retroactively removed and banned all the third party Google Voice clients already sold through the store). That was the first dickish shot of war--an act of unfair competition by Apple and AT&T--not this iAds business or Google making a phone OS
