You accuse him of "cashing in." If that is meant as a value free statement, my apologies. You then state that "he seems like an icon. Something long lasting."

Oddly, he just seems like an author, to me. If he is a figurehead, I missed that there was a movement. Is there more subtext to this? I assumed he just had a good seller. Oddly, many people can and do lay claim to that honor. It neither diminishes nor distinguishes it.
