Regarding the regulatory changes, I'd be happy with one of two things:
A) Governments impose restrictions on third party developers that are largely similar to the consumer protection standards that Apple has imposed on developers, while opening up alternative payment platforms.
B) Governments impose restrictions on Apple to prevent Apple from preying on their customers.
However, governments are going down the path of removing whatever protections the App Store provided consumers, without replacing those protections with any other pro-consumer regulation. This is the absolute worst case scenario for me. We've seen time and time again how developers will prey on their users, particularly with subscriptions.
