Your response lost me a bit.
Do you believe that you should try to pass a cyclist when he raises his arms in victory before the line?
(My position is you should).
Do you believe a runner should try to pass another runner before the finish, even if he is engaging the crowd?
(My position is you should).
Aside: I do appreciate the occasional athlete who cedes a position to a runner who had them beat and took a wrong turn right at the end. But they have no obligation to do so.
