In either case, this thing will die with a whimper, not a bang. Apple will have to concede to EU and it would not surprise me if other large markets will demand the same.
So the stage is changing. Apple could have flown under the radar and made concessions with terms they could dictate, letting them simplify their offerings across the world without attracting regulators and mega-lawsuits (and hear me out - maybe focus on products and innovation instead). Now, they fight against multiple jurisdictions at once, which all have different requirements (obviously, since they are different bodies). Even if they fold now, by reducing the tax and making more lenient rules, they’re too late. They already have regulators and judges dictating for them what to do, so their agency is permanently limited.
People forget that in the EU, the ”gatekeeper status” wasn’t just ”go after Apple and Google”. It was the App Store specifically. For instance, Gmail was evaluated but not included.
TLDR Apple has to sleep in a bed that they shat in themselves. They were universally popular and could get away with lots of questionable behavior, but instead angered everyone and are rightfully getting curfewed.
