Are people really trying to pretend that Epic had no clue what was going to happen? That Apple are just being petty? Come the fuck on. I have no horse in this race but it's pretty obvious Epic knew exactly what they were doing and were trying to leverage both Fortnite's popularity with gamers and UE4's popularity with devs to force Apple to budge.
Yep. Epic had a responsibility to their license holders who develop games using their software. Epic knowingly went and jeopardized all of that for a publicity stunt-you would think people would clearly see that, but instead we have people here defending Epic's decisions as good for developers!!
Unity is in the licensing and ad business and you bet your ass they wouldn't make a bone headed decision to put all of their customers livelihoods at risk.
