This issue happens evey decade or so. Last time it was wikileaks and VPNs being delisted by american credit card companies. That popularized cryptocurency and saw bitcoin rise as a censorship-beating payment system. And last week i signed up for a VPNs using my visa without issue. After that they went after filesharing platforms like rapidshare. Now "file lockers" are called "cloud storage" and are a normal online service. This time they are going after porn, an old favorite for US companies to hate. It will again come to nothing.
