If my parents are any gauge, most of us exJWs pay closer attention to what's in the magazines, broadcasts, and assemblies than they do. How many dubs read, pay attention, or even stay awake for these things? For the crapvention they'll hear the talks once, watch the videos once, might even take notes. A dose of the fear, obligation, and guilt may stick, but much of what was presented is completely forgotten by the time they get the breadsticks at Olive Garden on the way home afterward.
If they want to review the highlights of the program and watch the crapvention videos again and again, they'll have to get on "apostate" websites until/if it get posted on JW.borg.
