If this is 'harping', please keep doing it. Mass assignment/attr_accessible is an important and oft-neglected issue, and I appreciate your taking the time to help. I agree that readers could get the wrong idea by thinking they're better-protected than they really are. I've clarified the wording by adding "automatically" as a modifier: i.e., which attributes can be modified automatically by outside users The detailed meaning is then deferred to later in the tutorial, when the effects of attr_accessible are illustrated with concrete examples of mass assignment.
