Why do you think WoW has been running all these years?
Turning off your sub without complaining is not good 'voting', as it doesn't let the company know for sure why so many people are unsubbing. Maybe they migrated to a new game, maybe they can't afford it anymore because holidays, maybe there's something players think are terribly wrong.
If the game continues to add content players are unhappy with, even after continuously bringing it up, I'm sure many players will unsub and SE would have a good idea of the reasoning behind it.
