One of the major issues with the TPP is its effect on Freedom of Speech. Remember how everyone was concerned about the potential ramifications of SOPA and PIPA back when the US government was trying to crack down on “internet piracy”? Well, multiply that times a billion and then don’t run it through Congress, and you have, in a nutshell, the future effects of the TPP on the internet.
Under the guise of protecting intellectual copyrights, if the TPP goes through, the internet will change dramatically. It could turn internet service providers into watchdogs, and threaten our ability to communicate unfettered on blogs, forums, websites and social media platforms.
