The parent commenter is correctly pointing out that Apple would be able to disable the email for other reasons as well.
It's not like you can ask Apple to forward emails to your own email server if you decide that you no longer want to use Apple.
I think Apple shutting down your access is a legitimate concern. Yet Apple is the only one who has taken any steps to protect the customer here. The reality is we are unlikely to see other major competitors to Apple find a better alternative because their entire business is built on exploiting user data.
And 3rd parties who create a similar system are unlikely to be successful because they don’t have the clout to convince websites to incorporate them.
- Is there a big enough reason to motivate them to do so?
- If given a "legitimate" justification, would they?
If either of those are "yes" then the question we need to know is: "Is there any appeal, oversight, etc?"
With these emails they could trivially, and surgically, cut off a developer from every customer. It is a one-to-many action that also has no obvious other side effects (unlike bricking users phones).
Not sure where I stand with this, but wanting to point out that the added powers this gives Apple are very real and different from the ones they had before (again, maybe this is a good thing, but it’s undeniable that it is a different thing).
