Yep. Apple will be able to present this as evidence in any future court cases that while a reduced commission may be beneficial for developers, it does not necessarily reduce prices for consumers.
EU does care about developers very much even if USA doesn't. Credit card tax is the same, the store pays it and not the user, EU realized that 3% was too high for credit cards so they went after Visa and Mastercard and now it is 0.5%. They can get away with 30% in USA, but I doubt they will in EU.
