@daringfireball @gruber I find it really hard where they put the line is between monopoly abuse and bundling/integration. If Epic had a 60% market share in 3d gaming engines, would it be abusing its monopoly to make Fortnight while its competitors had to license Unreal? The iMessages question is even weirder—is the claim that Apple is forced to allow everyone to use its iMessage servers, or that whenever someone else comes up with a messaging protocol, they have to integrate it in iMessage?
