Steam (the game store) had an arbitration agreement. It turns out there's no class action arbitration and the merchant pays all arbitration fees. When they did something wrong (I don't remember what) and got inundated with thousands upon thousands of individual arbitration cases, suddenly they wished for a class action lawsuit instead. They removed forced arbitration from the EULA.

It's not clear if it meant anything anyway. Half the point of an EULA is to scare you away from trying to enforce your rights even if a lawyer would rip it up.
