I completely agree that the fight is about what rights a company has or doesn't have. I don't disagree with the fact that Apple has 100% control over it's own app store but I do think that there is a legit argument about where society draws the lines around monopolistic powers.
And my point about tribalism isn't about protecting your own property rights (with Apple's platform being Apple's property rights) which I full agree with, but around the increasing mentality of revenge, "winning" and hurting someone who "hurts" you back. Whatever stance you have for or against Epic, they had the right to sue Apple, and the outcome worked itself in court system. Yes, Apple has the right to do whatever it wants to do in their own app store, but I hope that these decisions are made for what's best for customers, and not simply to "get back at Epic" which is what some people are advocating for.
That's the point I was trying to make about tribalism.
