Replacing Mattrick is Zynga's much-maligned founder and former CEO, Mark Pincus. So what: The move is especially curious considering Mattrick was paid handsomely for defecting to Zynga in 2013 from his former role as president of Microsoft 's interactive entertainment division, including a $5 million signing bonus and stock options valued at upwards of $40 million to vest over a three to five year period. To be fair, Zynga also noted Pincus -- who still personally owns around 10% of Zynga's outstanding stock and has roughly 60% of its voting rights -- has requested an annual salary of just $1 for his role. Now what: Mattrick, for his part, stated he plans to "return to Canada to pursue [his] next challenge," and insisted he is "excited about the company's trajectory" going forward.
