It's the former Tumblr CEO. Technically a promotion from within but he was a recent hire as CFO.

There's a litany of such characters over the years; Al Dunlap comes to mind and his tenure at Consolidated Press Holdings.

Is this actually a strategy that is more common now? Trump is famous for this - he does outrageous things and then throws someone under the bus. That person leaves, they take all the reputational damage, Trump continues. Maybe Bezos and other billionaires are looking at Trump and thinking “Maybe I should go that far as well”?
