They appear to have ruled that Google has a monopoly because they’ve been squashing everyone else who should have been able to make an App Store by Google’s policies.

Apple isn’t squashing anyone, they just don’t allow it in the first place.

So I don’t think this would apply to Apple because of the line of reasoning. I know most people on hacker news think Apple should be forced to allow alternate app stores, but I don’t think this ruling can be used for that. It appears you would need something else.
