I’m just going to piss into the wind a little. After seeing what happened to Microsoft and Apple after they lost their founder CEOs, I don’t welcome this news as freely as others might. We’re not necessarily likely to see the company go directions that are for the better. (Maybe though this is really a rant about Cook. Amazon has lots of room to improve. Looking at all those forged brand names, for instance.)
Apple and Microsoft are arguably much better off today with their new leaders than they might've been. I don't see your point? I think Facebook, too, could use a new face at the top as a matter of fact.
There are real impact of not having a "product person" at helm. Business suits will squeeze out revenues and profits no matter what but there are no more tech that truly leap frogs existing art.
