Microsoft announced a new set of guidelines for its app store, including access to developers who meet privacy and security standards, as it started a push to win approval for its acquisition of Call of Duty maker Activision Blizzard Inc. Microsoft will file for approval of the deal in 17 jurisdictions, the company’s president, Brad Smith said in a statement. “Our goal is to make a universal store for games. In other words, a store that anyone can access on any device on any platform to buy or download any game that a developer chooses.”
