Did we really need another reason not to use the cloud? Not just iCloud, any cloud service. Back ups are easy and quick to do on external hard drives attached to your computer. I do it every day. My phone mostly contains items from my computer and the few things it does not I can back up to the desktop system
If you choose to believe Apple when they say they cannot access your device, that's your error, not mine. But I don't have an Apple phone anyway nor do I keep sensitive data on my phone, either.
Yes, I do have Macintosh computers as well as Windows systems. That doesn't mean I trust any manufacturer. OK, I am paranoid. But am I paranoid enough?
