> In the age of subscriptions, being able to see all your recurring payments on a single page and cancellable with two tabs without questions asked, is a feature worth paying for.
This is a service the banking system should clearly provide natively though - there's no good reason Apple is the only one capable of this, nor any good reason why they're best placed for this (there's plenty of non-Apple subscriptions where this would be useful).
Your card provider is well aware of what recurring payments are currently authorized, and should be perfectly capable of providing tools to cancel those authorizations (and inform the merchant of this when doing so).
That that doesn't work is a failure on the part of financial firms (who could provide it) and regulators (who imo should oblige card providers to offer this, and oblige companies to treat cancellation notification like this as equivalent to written notice). Recurring payments are an increasingly fundamental part of consumer banking, but banks provide effectively zero tools for consumers to manage them.
The argument against is that some of these payments might have ongoing obligations you can't just cancel without consequence, and you'd be effectively just be refusing to pay your bills - but you could equally well have no balance available or something so the payment fails in existing cases anyway, so this seems like an entirely solveable issue (if a business that you _must_ pay receives a notification that you've cancelled the card billing authorization, they're going to need to get in touch with you about it just as if your monthly charge failed).
