Never going to happen. People are too busy with their own lives to worry about joining some protest over seat fees...especially considering most travelers are of the infrequent variety.
If you want fees gone, forget about trying to persuade individual travelers. You have two options. First, you can convince government to ban the fees. Second, you can get the airlines' best customers to demand the fees disappear. Those best customers are the corporations that purchase thousands of seats each year.
