Every other F100 was outsourcing IT like crazy in the mid-2000s because of that Harvard Business Review article that talked about outsourcing everything non-essential to your primary business. Meanwhile, Werner Vogels (Amazon CTO) thought that was a stupid idea because every business was being transformed by its IT and that it's a revenue multiplier, not a cost center (something that every other decent person in the rank and file of IT has believed since... ever). The whole "digital transformation" boom that swept the F100 in the past 10 years is essentially back-tracking on all these divestures and off-shoring efforts.
