Irving had largely opposed the strategy that Thompson has been aiming toward, said sources, and also strongly disagreed with laying off so many employees without a clear plan in place. Many inside and outside Yahoo agree.

There is no word on what Irving will do next, though sources told All Things D that he has already had several offers.
