WPP and IBM did an internal outsourcing deal.
Most of IT employees laid off by IBM, after being rebadged from WPP and IBM.
At the same time, IBM cost a to for every WPP opcos, with a huge decrease in quality of service. (See petya attacks, because IBM did not properly patch workstations) - both companies act recklessly and only care about profits (nothing wrong with profits but it cannot be the only driver).
