Yeah. Apple doesn't want you to jailbreak because it means you leave their control. So, they pull out the worst events that can happen from jailbreaking and make it seem as if they are all a common occurrence - thereby justifying their position of opposing jailbreaking.
Never mind that these are all extreme circumstances that in many cases can be resolved or mitigated. Either by common sense or awareness. In most cases none of this is an issue at all!
My iPhone pretty much works they way I want it, I get excellent battery life and I really don't have a ton of issues and most of the issues I do have are minor or just because of iOS 7 itself.
Your mileage may vary of course, but Apple will always amplify the worst.
