I strongly suspect this push to change Apple's App Store is not coming from Apple product users. It is coming from people on competitive platforms who want to take away Apple's competitive advantage. Despite that, Apple cannot just pull out of territories because more of these laws will be passed in other places. What they need to do is start trialing some of their countermeasures they have been working on for this eventuality. Developers believe they have won a free ride. I rather suspect they are in for a very different kind of ride.
Apple should give developers and consumers compelling reasons to continue to use apple's payment service.
E.g. loyalty points to be redeemed against apps/products, ease of use in payment management (e.g. a better 'cancel my subscriptions / pause my subs process), better data on spend, price guarantees, and so on.
