It doesn't seem to me that the intellectual property provisions of the agreement are all that important to the overall stated goals of the TPP. Yet they are so fucking regressive and antagonistic that there is some chance (I guess? Again, echo chamber...) that they will sabotage the rest of the agreement. After SOPA, etc., if it were me and I wanted to be sure that the TPP passed in enough Pacific Rim countries to make it effective, I would keep anything remotely like SOPA as far away from my precious treaty as I possibly could.
Instead, the IP portions of the agreement are basically the language that was in SOPA all over again, which pissed a whole lot of people off last time. It's really hard to take seriously the claim that the TPP is so important, when the people drafting it are including language that is pretty much guaranteed to stoke vigorous opposition, for reasons that are mostly orthogonal to their goals.
