Epic Games has filed a lawsuit [1] and published a Fortnite-themed parody of Apple's "1984" [2] to get some publicity for it.

The idea that a large platform like iOS can only have apps loaded through a market place controlled by the hardware manufactured is clearly in violation of the spirit of anti-trust laws.
However there's no legal precedent on this because no one with deep enough pockets to fight Apple has been angry enough to do it yet.
Meaning this could be great news for everyone if this goes to court and Apple loses as they should.
