The government should require credit card companies to introduce a system for recurring billing which would let you see all your subscriptions on your credit card web site and cancel them there. For the 3.5% they charge in fees it is the least they can do.

Sure but until that happens the App Store is the next best option.

I as a consumer would like a choice in the matter. Pay 30% more for a subscription dashboard or pay 30% less and cancel from the developers website.

And under this decision, you will be still be free to only subscribe to apps that go through Apple and allow you to cancel that way

Hmm. I'm already considering switching our app to stripe only to ease billing reconciliation. Managing users who made in app purchases who want regular web access as well has been a pain.

Perhaps the added competition will encourage Apple to improve this, they haven't had any reason to make it better so far.
