If the PwC tax leaks scandal demonstrated one thing about PwC International, it’s how introverted it is – these people really don’t like sharing.

They don’t want anyone to see the international report they commissioned; they don’t like naming international partners; and they really don’t want to share the names of the “dirty 34” US tech giants they targeted using confidential Treasury information with fixes for the Multinational Anti Avoidance Law (MAAL) before it came into effect in January 2016.
