Amusing conspiracy theory time!
Epic is acting on behalf of Tencent whom the US have recently started acting against with 2 specific actions limiting other companies to trade with some of their massive mobile platforms. The whole thing is only aimed at tying up the two primary American cellphone companies and providers of cellphone applications in a legal and public opinions battle trying to paint both market leaders as bad actors while portraying themselves as champions of the people as they launch their own line of cellphones(probably huwaei or xiaomi) and/or a mobile OS. They don’t need neither Apple or google to fall or be broken up, it’s all a publicity stunt to get a foot into the door and they’re hoping to rouse their largely under age fan base to jump aboard once they launch their own thing.
Or maybe Tim Sweeney just have too much money and too few marbles left and think that he can do whatever he wants by just throwing enough cash around.
