What would be very interesting would be to see sales and profit numbers for that brief period during which Epic added the option to pay outside of Apple.
If Apple is arguing that Epic "hasn't shown that the anti-steering provisions have caused them harm", would it change the game if simple profit figures showed that during the time that Epic ignored those provisions, they made a larger profit?
I dunno, to me it just seems to be one of those "duh, that's obvious" things - if someone orders you to give them 30% of your income, and then tries to say "oh, that didn't cause you any harm"...
IANAL, but perhaps it's how "harm" is defined? I mean, if you have 100 million dollars cash and someone orders you to give them 30% of it, you still have 70 million dollars, you'll still be fine. But if you barely make enough money to make rent and pay bills, and someone orders you to give them 30% of it, that 30% can mean the difference between being able to pay your bills and being evicted. But if that's how "harm" is defined, then it'd be hard for ANY large company to claim "harm" unless said company actually went under or something due to the practice. And in that case, shouldn't Apple have to prove that NOT having the 30% cut from Epic caused them "harm" (which it clearly wouldn't?)
