Apple makes it incredibly difficult to tell what information is being shared/gathered and where it's going. You actually don't have to opt-in to iCloud backup of everything on your phone. If you have iOS 5 or later, you are automatically connected to iCloud, and all of your files are backed up there. It's all in one of those ginormous agreements that no one reads when you update your phone's operating system, or activate your new phone.
I would wager that most people who have iPhones are not actually aware that their data is already on iCloud. It's not so much a case of "How would anyone entrust their information to the iCloud" -- it's more of, "How did my information end up there without my knowing?" And, theoretically, having your iPhone data backed up on iCloud is no different than entering your credit card information online -- the information is encrypted and supposedly stored safety. Do most of us still feel a twinge of anxiety when we type in our credit card number on Amazon or Telecharge? Or when we log into our bank's website? Or when we are logging into our employer's network through VPN or WiFi. iCloud is no different from any of those things.
The fact is, life in this age entails entrusting your information to a variety of servers. Some of those servers are more secure than others, but nothing is ever 100% secure. iCloud is just a small drop in the bucket in terms of how much of our information can be hacked into. How sheltered do we expect people to live their lives?
Although it's unlike anyone would want a random stranger's photos or non-financial info:
