the line is crossed because if you store data in the cloud you kind of get that the provider might be force to give LE to it. It may or may not happen but if it's in the cloud technically it's out of your control.

Stuff running on your device OTOH, you have the illusion that you control it. It's YOUR physical device and technically you should be able to do whatever you want with it. Now, enter closed source software + walled gardens => you don't really control your device. You don't get a say on what's going on in it. Up until know we believed Apple would do the right thing. Well... Myth busted I guess.
