The problem here- if I understand correctly- is not that companies were voting with their wallets, even together. The problem is that they were willing to do it only as long as all the others were doing the same. Some companies standing by their principles, and willing to pay the price for it, is one thing. Making sure that nobody else benefits from the space you leave is another.
