Apple is not about being open. It never has been. Every app on the iPhone (all 50,000 of them) must be approved individually, for instance. This difference in approach wasn’t a problem until Google started to have mobile aspirations of its own. Asked to choose between furthering Apple’s mobile agenda or Google’s, Schmidt must choose Google’s. It is his fiduciary duty. That conflict is only going to grow. And that is perhaps why Jobs says his “effectiveness as an Apple Board member will be significantly diminished.” Also, the more they compete, the more they expose themselves to antitrust questions from the FTC as long as Schmidt remains on the board.
