Developers are also not allowed to link to account management on a webpage if they signed up via a website, which contributes to lots of user confusion when it comes to cancellation of a subscription for instance.
Correct me if I'm wrong.
This is the only statement that might be construed as such from the article, but it doesn't say anything about management, and I'm really not sure what consent means - is it a popup that says "do you want to be informed about non-apple payment methods?". Maybe it is what is being changed, but I can't really tell.
I can say that customer confusion is often built into app store policies, and the amount of backend and customer service work to clean up users who sign up with multiple payment methods accidently is not a trivial cost.
