PUBG Corp SUING Fortnite/Epic Games Over "Similarities"?

Will the legal precedent regarding what violates copyright in the gaming industry be changed if PUBG Corp successfully sues Epic Games? Or will Epic Games revoke PUBGs Unreal Engine 4 license like they did to Silicon Knights' back in 2007 for attempting to sue them? OR is it all one big PR stunt for marketing (the most likely case in my mind). Corporatism runs our lives and infects the gaming industry.

This is my take on the recent news that PUBG Corp is suing Epic Games. I read a couple articles and give some background on the situation, and of course my thoughts on it. Let me know what your thoughts are in the comments?
