I think Jobs is just filled with envy. First was envy towards MS and it's chief, Gates, because the whole world chose MS Win and, not least, because Gates has more money than him.
Now, it's Google and Schmidt, because the whole world uses Google search and probably Schmidt has more money than him.
Besides, he hates the fact that other people can come up with better ideas than himself. Praising others' success is just not in Jobs' vocabulary and he can't stand the fact that people appreciate his competitors. That just fuels his envy and sourness and the whole cycle repeats.
