Well, this is the best explanation I have ever read about what went wrong at Ebay -
"asleep at the wheel or willfully blind" "the worst corporate governance I have ever seen"
Wed Feb 18 22:58:28 2015 @Marie, JD has his own backpocket in mind. He came from Bain and is an asset-stripper. Carl Icahn called him "asleep at the wheel or willfully blind" and Icahn called for JD's removal as CEO (which is happening this year). Today, Icahn dramatically increased his stake in eBay yet again. Icahn pushed for the spin-off of Paypal (and that's happening this year also). Icahn also called JD's management "the worst corporate governance I have ever seen".
