One hypocrisy is that while the TPP aspires to more-perfect law enforcement around copyright infringement (to be a shared responsibility between member nations[1]), imperfect copyright enforcement has played a role in the success of some products of the (now incumbent) companies. Most recently, in Facebook's rise to compete against YouTube, "freebooting", a practice whereby random Pages steal YouTube content without attribution, has been a major issue that is only being addressed after critical popularity has been achieved in Facebook video numbers.

"Venice’s elites were the chief beneficiaries. Like all open economies, theirs was turbulent. Today, we think of social mobility as a good thing. But if you are on top, mobility also means competition. In 1315, when the Venetian city-state was at the height of its economic powers, the upper class acted to lock in its privileges, putting a formal stop to social mobility with the publication of the Libro d’Oro, or Book of Gold, an official register of the nobility. If you weren’t on it, you couldn’t join the ruling oligarchy."
Many corporations did not have the opportunity to add their wishlists to TPP negotiations, e.g. to use a trade treaty to hijack law enforcement to slow business model competition and innovation in digital trade. These excluded corporations have many reasons to oppose the TPP's proposed entrenchment of their competitors.
