For now, I think the majority of bandwidth would be the zillions of iPhone users doing backups and app updates all the time. However, this is definitely a way to pave the path for Apple TV+.
That’s a sure-fire way of getting dataloss. Wouldn’t it be much easier to just upload the backups from users devices when, idk, at night? iCloud requires your device to be locked, connected to WiFi, and charging, so I imagine that already shifts the traffic to off-peak hours.
