There is no law saying that epic can’t be banned from Apple’s AppStore. That’s just not a thing.No it does not make sense. Apple is not a house, it’s a company. And company have to comply with strict laws and regulations. They can’t make up rules and ban those who do not follow them.
We can argue that there should be a way to install apps from outside of Apple‘s wall garden, that’s a perfectly fine argument to make, that I agree with in theory.
But even then, there is absolutely no law, nor should there be a law, saying that Apple has to host epic games on the US AppStore. If Apple wants to ban Epic for any reason they are perfectly in their right to do so, just like Google can remove your video from YouTube if they don’t like it and there is really nothing you can do about it.
