Class action lawsuits are about people punishing companies because the government won't levy a harsh enough penalty. I never took part in a class action because I wanted "a payday," I take part in them because I want the company punished.
Shouldn't they have an arbitration clause in there somewhere? Maybe that would open them to a Thousand Papercut bleeding when everyone activate the arbitration clause at once.
Wait until Robinhood sees the class action lawsuit
