Time to see what the next move for Apple will be if they lose the appeal. Because I doubt Apple will be content to lose money on the ruling and will look to collect the fees elsewhere. Without the ability for developers ship iOS apps with no business relationship to Apple you're still pitching your tent on someone else's land.

If there is one thing I've seen Apple do reliably over the past 20 years, it's being able to comply with rulings in the most malicious and hindering way possible. They'll be just fine with no difference to their bottom line.
