If the phone were to simply reboot rather than show a blue screen, and then reboot, no one would care about this issue. It would just be another bug in iOS 7. The media just seems to enjoy any sensational twist to the story.
iOS 7 is buggy, get over it [I'm a developer, I've been on iOS 7 since the Betas, it's still buggy]. Hopefully 7.1 (and please, Apple, 7.2 and 7.3) will fix a lot of these issues.
