Well, if you want to buy a product and only Home Depot has it, or Walmart... then it's what there is available. We also use cars that pollute. Facebook is a market place for people to gather. If there is an alternative, it could grow to the size of FB as well. I think you have good intentions, but it may be a bit too far. It would be better to have better corporations, but they have also provided a high standard of life by providing lower costs of living for many. Alternative that are better are always welcome, but often we re limited in what we can do otherwise. I don't have a car, I bike or use public transpo, but I understand the need for vehicles in people's lives.
