If this is the result of sabotage, it puts SpaceX's previous launch failure in a different context: any entity willing and able to take a shot at and destroy a rocket from within the confines of Cape Canaveral might also have been able compromise a strut provided by an outside entity.

I find SpaceX's predicament to be deeply troubling, maybe because if this is sabotage, it casts a pall on the humanity's ability to make progress.
