Does anybody else remember how well they used to get along? Here's Epic demoing Fortnite at WWDC15: https://www.youtube.com/watch?v=ChIuImrOsaY https://www.youtube.com/watch?v=ChIuImrOsaY Ever since the Citadel and Zen Garden demos, I remember Epic getting a prime spot or mention at almost every WWDC, where they used their tech to showcase Apple's and vice versa, like the power of modern iPads and Metal. What do you think must have gone down behind closed doors for their relations to have soured to this point? Unless of course it's all a calculated stunt that ultimately benefits both companies.
