Let's be realistic here. FreeBSD users don't have a choice of package managers. It's pretty much PKG or nothing.
So what? Choice does not define an economic market. Competition does. Can't use Apple's AppStore on Android! Google is a monopoly!
These details do not matter. You have a choice. You want iPhone, you're stuck with AppStore. You want Android? You're stuck with PlayStore. You want FreeBSD? You're stuck with PKG. It has always been this way. Linux proper gives a few choices, probably dozens. macOS has the Mac AppStore, but also can use MacPorts, Brew, you can even use pkgsrc if you want. iOS is maintained as a walled garden for security. And, you can still jailbreak it and use Cydia.
Apple is doing nothing wrong, protecting their IP and their walled garden. Don't like it? Go elsewhere. Epic is acting like an infant, and chewing off their own foot while they do it. It is all absolutely absurd. What a waste of resources. At least the lawyers are happy.
