It isn't like its the wild west out there; we already have strong copyright legislation. What the TPPA is seeking is corporate control over the ability to exclude people from the internet at will, with no judicial oversight. To a large extent it already does; I dared to critique the Business Software Allience on YouTube and my account was closed. No comeback here - to challenge it I would need to agree to defending myself in California. Unless you are a U.S citizen there is no fair use or free speech on YouTube, Facebook, Google, Yahoo etc. You are there at their pleasure, and easily ejected.
The TPPA seeks to extend this power to your local ISP; to actually cut you off from the net totally if you are saying things they don't like.
It isn't about protecting works, it is about controlling the channel. The Internet was a danger to corporate control of how people got their entertainment and information. They are now getting the people back under control, subservient to their masters like they should be. The thing is that most are happy with having their entertainment and information fed to them, told what they should be angry about.
The risk to Hollywood isn't that we will steal their content - it is that we will discover their content is gilt covered crap, and that we can beginb to express ourselves without getting one hundred million dollars from a VC. What the RIAA and MPAA care about is making sue that they control the music we listen to and the movies we watch.
That is the focus of the TPPA. Control.
