I am not sure if it is the wizard setup, but when it has updated iOS, it reboots, and on first boot I am greated with multiple prompts to start using each of these services, in a similar way than if it was a new iphone. But this is not for new features. The same prompts come back at every update, even if I opted out many times before.
I do think that "harassed" is the appropriate term for this repetitive nagging.
