Put your money where your mouth is! I have preached this as an effective way of keeping democracy working. Amazon kicked Wikileaks of their servers. Paypal closed their account. I will put my money where my mouth is and have closed my accounts at both companies and their subsidiaries. I am sure their competitors will be happy with my business.
Updates: I now add Mastercard to my blacklist. Visa, you got a new customer, not. Better late than never, Bank of America will not have to deal with me as their customer. Following the dubious practices by SONY, I have decided to support other hardware makers.
