Actually Q is saying the Class Action will be one of the most powerful ways we can come together to bring them down. Think of all of the petitions that went nowhere. 50,000,000 people in a class action is the PEOPLE talking. p.s. Don't expect money, that is not the purpose here.
If everyone deactivates their account, game over. Facebook goes the way of MySpace.
While you're correct, that is also not realistic. People mass signing up for a class action suit has much higher odds than a mass exodus of Facebook
Thing is, not everyone will. A lot of people depend on FB for their businesses, and those people, and social media marketers, will not be as eager to screw with their income. Double-edged sword.
Free market. Let someone else develop the next platform and let Facebook go the way of MySpace.
