Furthmore, why is it when you delete a photo from your iPhone it can persist on iCloud for up to 30 days?
Likewise, why is it when I restore my iPhone and set it up from scratch it starts to download 100MB + of data over WiFi? [1]
[1]. When I setup my iPhone from scratch (Apple ID, iCloud disabled), it hammered my WiFi at the full RX rate of my DSL line for approx. 10 minutes. That's 4Mbps * 60 * 10 = 2400Mbits = 300MB. I made sure that my iPhone was the only device connected to my WiFi. What could be in that 300MB of data? I should proxy all traffic from my WiFi to my DSL modem via another PC and do tcpdump on that!
I'm sure if I choose the same option in Windows 10 a large part of the OS will be completely closed off.
Edit: Apparently they deprecated it inside the app itself, not in the store. I've kept the message above.
