A blurb from the site:
TPP raises significant concerns about citizens’ freedom of expression, due process, innovation, the future of the Internet’s global infrastructure, and the right of sovereign nations to develop policies and laws that best meet their domestic priorities. In sum, the TPP puts at risk some of the most fundamental rights that enable access to knowledge for the world’s citizens.
The USTR is pursuing a TPP agreement that will require signatory counties to adopt heightened copyright protection that advances the agenda of the US entertainment and pharmaceutical industries agendas, but omits the flexibilities and exceptions that protect Internet users and technology innovators.
The TPP will affect countries beyond the 11 that are currently involved in negotiations. Like ACTA, the TPP Agreement is a plurilateral agreement that will be used to create new heightened global IP enforcement norms. Countries that are not parties to the negotiation will likely be asked to accede to the TPP as a condition of bilateral trade agreements with the US and other TPP members, or evaluated against the TPP’s copyright enforcement standards in the annual Special 301 process administered by the USTR.
This has also likely been posted a few times on here before.
