Is Cindy Sheehan really out for personal gain?

I heard cindy sheehan is holding out on selling her story for millions. She reportedly was offered an amount of money for her "Grief and anti war movement" struggle , she originally said she can't sell her thoughts but will disclose them when the time is right. Now she is saying that an offer over 5 million dollars will get her story. Casey would be proud his mother is profiting from his death.
