Are Quakes fans completely powerless against John Fisher?

Serious question, is there anything Quakes fans can do besides going to games vs not go to games, buying season tickets vs not buy season tickets, complaining on BigSoccer vs not complaining?

Do San Jose Earthquakes fans have any recourse other than accept the situation for what it is, keep showing up (or not) and make the most of it while we still have a team in San Jose?
