I know how you feel, Wild Thing...
Each person, with their own experiences, personalities, will have their different reasons to attend or not to attend.
Me? Though I would never want to hear another "memorial"/ advertisement/ recruiting talk, something inside me would want to 1. Make a statement: "Here I am, you shun me, but I am not afraid 2. Face what you have done, you can't have your happy little JW world without thinking of what you did. 3. Maybe, just maybe, someone wished they knew, are hoping to escape and need the support. 4. To observe it as a matter of history.
Maybe....
Just me, cha ching
