Safety and trust. I know in app purchases are handled through apple and if I start a subscription, I know how to easily cancel it. I don't need to worry about my payment information being stolen or held hostage behind a convoluted cancellation process.

> convoluted cancellation process

probably the most important thing here. One press in the settings app vs calling some retention person that tries to keep you paying or something that can only be cancelled via fax or carrier pidgeon

But having choices doesn't mean that the "Safety and trust" of the app store will go away it simply means that I can choose another option as well.

Couldnt Apple just say apple pay is required but other processors are allowed? Think you're being a bit obtuse here.

How is allowing many 3P payment processors a feature? It's a complication and an added risk with no upside for me as the consumer. No thanks.
