1. I think we're assigning different meanings to "out of one's control": If you can "have a plan for it", as you say, than I wouldn't call that "out of your control", even if it's not your fault. In your example, the unfolding of the sunshield wasn't out of NASA's control, even though a failure might not have been anyone's fault in particular, so NASA would have been the one to blame. In contrast, an untracked meteorite hitting the JWST after launch would have been out of NASA's control.

2. Yes, that's what I meant by "for diplomatic reasons" :-)
