Another one of Siri’s daddies is leaving home. Bloomberg reported on Tuesday afternoon that Siri co-founder Adam Cheyer was parting ways with Apple (AAPL) just two-and-a-half years after the electronics giant acquired his company. Unnamed sources told Bloomberg that Cheyer had left the company “recently” after spending time with Apple’s mobile software group. The sources did not list a reason for Cheyer’s departure. As Bloomberg notes, Cheyer is the second major Siri-related departure from Apple over the past two years as former Siri CEO Dag Kittlaus left the company in October 2011.
