But it’s not? Like if they block that subdomain, they will completely block Sign in with Apple.

Many web sites and apps do not use Sign in with Apple. And they could block the domain for account creation with email without blocking the domain for account creation with Sign in with Apple. This would not make sense unless Apple changed what personal information Sign in with Apple provided probably. But they could.

You can use Hide My Email independently from Sign in with Apple.

I know that, but in doing so you prevent yourself from ever using Sign in with Apple

I think you as the user can use the aliases without Sign in with Apple though, right?

But otherwise, you're right, any website that wants to accept Sign in with Apple will almost certainly be agreeing to Apple's TOS for Sign in with Apple I presume will stop you from blocking this service.

Why would they care about this?
