I’m not sure how the point stands. The iPhone was introduced during that tenure, then the App Store, then Jobs decided Google was also headed toward their own full mobile ecosystem, and released Schmidt. None of that was a conflict of interest at the beginning. Jobs initially didn’t even think Apple would have an app store.
Talking about conflicts of interest in the attention economy is like talking about conflicts of interest in the money economy. If the introduction of the concept doesn’t clarify anything functionally then it’s a giveaway that you’re broadening the discussion to avoid losing the point.
You forgot to do Oracle and Tesla.
