Mastercard and Visa shouldn't be controlling who you can do business with

There exists file sharing sites that share that contain copyrighted content, but the idea that financial transaction institutions such as Mastercard and Visa working with the MPAA and the RIAA to preemptively block financial transactions with organizations they don't like sets a chilling standard with regards to the freedom of to whom you are allowed to do business with. We are seeing the same thing happen with Mastercard and Visa blocking financial transactions to Wikileaks because of the inconvenient nature of the material they are publishing online. Supporters from around the world are willing and wanting to donate to Julian Assange and his cause through both financial and technical support.

There is nothing more democratic when it comes to people voting with their money, which is exactly something that the US claims to be a staunch supporter and defender of. Unfortunately this simply isn't a battle of ideals, free markets or rights. It's simply organizations trying to change the game to keep other people out of their political/economic turf.
