There are a lot of big name companies opposing this treaty, including ones you wouldn't expect. The "Intellectual property owners association", which is headed up by representatives from Exxon Mobil, GE, and Johnson & Johnson wrote a letter opposing the treaty. Their concern is that they think it sets a bad precedent... get this.. for PATENT law:
By isolating L/Es (limitations and exceptions) from the IP holders’ rights, the VIP (visually impaired persons) treaty negotiations could also set a dangerous precedent for other areas of IP law, particularly patent law.
Let's ignore the massive expansion of copyright without any mention of fair use through free trade agreements, and complain that the one real attempt to clarify limitations and exceptions is "imbalanced." Also from the letter:
"A balanced approach to copyright protection cannot exist when rights and exceptions are treated separately."
That's true, but not for the reasons they think.
Basically, they are saying they would rather blind people have fewer things to read than to even HINT that copyright protection is currently too strong, since that might possibly induce people to question other areas of IP law, like patents. They ought to be ashamed.
