I see it in private industry too, I just worked in 2-week sprints on something only to discover that all our "feedback" for the past six months was actually from (surprise!) the managers in the pipeline, who hadn't actually enabled the feature to be seen by real end-users.

Among many possible causes, two that come to mind:

1. Managers who (despite lip-service to the idea) refuse to take any incremental risks looking bad with negative feedback each sprint, and would rather risk one big failure-event.

2. Companies which have either very-convoluted procedures or who try to treat end-users as cheap interchangeable human-robots... Which means no change can ever be rolled out without exhaustive documentation and training plans. Therefore all changes have to be "big enough" to be worth it.
