Earlier quoted context omitted.
Epic effectively pulled it themselves when they unilaterally broke their agreement. I think Apple's cut is egregious but at the same time, they're not a monopoly. My main gripe is that they're behaving as if they're bringing value that the developers are riding on, when in reality nobody would buy iPhones if it weren't for the value that many developers are bringing to the platform, often at no cost to Apple.
Who else is apple competing with to put apps on iphones? Compared to android where you have indy devs, samsung store, play store, or any other store; it's a clear monopoly.
Their strategy also adds a lot of consumer value. I use an iPhone specifically because I understand the tradeoffs between freedom and reliability/security, and I go for the reliability/security. Not everyone wants a second job playing sysadmin on their smartphone.
