Heads I win, tails you lose

Or, here's a naked statement of self-interest without any particular warrant for why I ought to care:

"We really don't want to establish a precedent on a series of treaties that specifically focus on trying to set forth minimal limitations and exceptions to the rights of copyright owners," Alder [a top lobbyist with the Association of American Publishers] told KEI in Geneva. "Up until now ... the treaties and other international agreements that have been devised ... have been to establish the minimal rights available to copyright owners, not the limitations and exceptions to those rights."

I think we're all pretty clear on that.  It's the why that we wonder about.
