I'm going to laugh about this all day.
If only we had a word that was a synonym for example in which the underlying elements share a common theme. We could call that word something like..... analogy... or something.
I know I shouldn't interfere with your little spat with Nebula, but here goes.
He wasn't saying that his Coke truck example was completely analogous to the iAd/AdMob situation. He was simply citing an example where competitors elect to not benefit their competitors.
Believe it or not, not every example has to be perfectly analogous to every aspect of an original concept. For instance, I can compare traveling by boat and by airplane even though a boat doesn't fly. (For reference - you were upset that his coke example didn't exactly match the iAd/AdMob situation).
