Apple  (NASDAQ:AAPL)  isn’t taking it easy in its now-litigated fight with Epic Games, countersuing the  Fortnite  game maker for breach of contract over the in-game payment system it created to bypass the App Store. “Although Epic portrays itself as a modern corporate Robin Hood, in reality it is a multibillion-dollar enterprise that simply wants to pay nothing for the tremendous value it derives from the App Store,” Apple said in the filing. It also took a swipe at Tencent  (OTCPK:TCEHY), owner of 40% of Epic: “Tencent (which has its own competing app store, one of the largest in the world), also seeks to dismantle the App Store’s entire business model to advance its own economic interests.”
