This would be a customer action — it affects one person. Unless you’re implying they’d disable the phone of every user of a certain app or something to that effect.

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).
